It would be irrational to pay for a service you are unhappy with. Perhaps you mean you are are "unhappy" in the same way that one is "unhappy" to have a $5 BigMac over a $50 steak? Which is to say that the BigMac is good for the price, even if not the best food imaginable.

Just about anyone (with reasonable knowhow) can provide you phone support. If there are fewer than 20 people out there willing to do that for you, I'd be flabbergasted. But they won't work for free, and probably not even for cheap. You've no doubt chosen the bargain basement option provided by T-Mobile because you find it balances the best value for the money. It's not great service, but it is cheap service. It's the $5 BigMac, even if you are really craving $50 steak, but don't want to spend $50 on a meal.

We seem to be flailing around here a lot, but it was made clear to me in the last comment that we're talking about the phone support being paid for. Phone support does not have to work directly for the telecom to interface with the telecom. They can talk to you to find out the problem and then do whatever it takes to get the job done with the carrier afterwards.
How much are you actually willing to pay for that, though? It seems the answer is not much. So why would competition rise up to make no money?
Let's take that further: Why aren't you offering this service to others? Because you realize you won't make any money?
