You do understand people can tell you a story like that about every carrier, but that doesn't mean its the norm. Moreover, there are plenty of people happy on Sprint. Currently, it has been rated the most improved carrier, and gets strong customer service marks. Not sure why'd you want it to close, as opposed to reform itself to give people more options.
I have an AT&T story. I heard AT&T advertise high speed DSL in my area for $19.99 a month for a year. This ad was on the radio. I then saw a commercial advertising the same thing while watching the TV show House. I was interested. So, I go to AT&T's website, and saw the same pricing listed there as a special. So, the website makes you type in your address to verify it is available in your area, which the website based on my address concluded it was and I proceeded to sign myself up for the offer. AT&T send me a confirmation of my order being accepted.
Two days later I received the router. A day or two later, a service guy visits to turn on the service. It doesn't work so, so I call customer service. I was bounced around to numerous people, each time having to re-explain my story. Apparently, AT&T couldn't figure out what department I should be speaking with because it couldn't find confirmation of my order despite being billed, the service guy coming out, and receiving the router.
After figuring out I did in fact place an order and service was turned on, I eventually was put through to the tech guys who couldn't figure out why the Internet wasn't working. The guy I was talking to promised to get back with me, which he never did. A week later I was still without Internet. The second week after my service was supposedly connected, I contacted several customer service representatives who each told me they will get back to me when they figured out the source of the problem.
At the end of the second week, after an hour on the phone, I finally found a customer service person who spend some time searching the records who then tells me the service was cancelled by AT&T the same day it was turned on. I asked why the service was shut off, and why I wasn't told. The representative explained that the $19.99 pricing wasn't available in my area. I directed the representative to the website that clearly established that it was advertised as available in my area, and that AT&T accepted my order. The very nice person told me the advertising was incorrect, and he couldn't honor the advertised price despite it being AT&T's error.
The third week, I made it up to a supervisor who promised me he'd take care of me and compensate me for the error. He promised to give me a free box, which I was originally going to have to pay for. I thought cool. He then told me he credited my account, and he needed to put me through to another person who'd get some basic information from me and turn the service back on. This new person took my information, said the service was scheduled to be turned back on the next day, and the price would be $42 a month. I explained to the lady I was supposed to be signed up for the $19.99 plan, to which she said that wasn't available in my area. At that point, I asked for AT&T's legal department.
I called the legal department and left a message. A few days went by without a response. I then made a complaint to the State's Attorney General's Office alleging AT&T was violating consumer protection laws by not honoring a price it clearly advertised. Meanwhile I called AT&T's legal Department again and managed to get an actual AT&T legal representative on the phone. This was about four week after I ordered the service and was billed. I explain to the lawyer my story and told him that when AT&T advertised the $19.99 offer, and I accepted it, AT&T and I had a contract. By not honoring the price, AT&T was breaching the contract. I explained that I planned on filing a Class Action lawsuit based on this clear attempt to engage in illegal bait and switching. The guy told me AT&T would honor the price and have the service turned on that week.
So after my service was working for a week, I get a call from some other person at AT&T who left me a message saying AT&T received an inquiry from the Attorney General's Office and AT&T wants to address my complaint. I called the person up and left a message explaining the issue was already corrected. That person calls me back and leaves a message saying the plan was changed from a $42 plan to a $26 plan (mind you this was after the AT&T legal representative corrected the matter to reflect the $19.99 offer). A week later, I get AT&T to correct that.
Now you might wonder why I spend so much effort dealing with this horrible company. Well, in my area I have two choices for high speed Internet. Comcast for cable, and AT&T for DSL. I changed to AT&T because I had a dispute with Comcast where it promised to send somebody out to fix my Internet, but the person would never show. This happened three times in a row. Further, I couldn't get Comcast to bury its cables it had wrapped around my trees. I was so upset at Comcast, I had it remove the cable from my property.
I am sure my experience isn't representative of the company as a whole, but that is my point.
