I was an AT&T customer for about 6 months. I really cannot overstate how terrible they are. I've never had any desire to seek power, but dealing with them made me wish I could be dictator for a day just so I could dismantle the company.
AT&T is a Frankenstein of a company that is simply chewing through customers with a horrific combination of incompetence, and actual malice.
45 days before my contract expires with AT&T, i signed up a new service with T-mobile, i also ported my number to T-mobile.
With in a week, i got 150 bill for breaking the contract. I argued that i never asked to cancel the service. I want to pay my last month bill and complete my contract.
Nope!
AT&T cancelled my service because i ported my number. I ended up paying them 150$ just days before my contract expires. No prorated no discount.
Never ever going back to anything related AT&T. Never.
Did you check the contract to see if porting your number meant canceling your contract? If it didn't mention it, then you take them to small claims court, then when they don't pay after they don't show up, you go back to court and get a writ of execution to perform a till tap at an AT&T store.
If the law in your jurisdiction requires more than payment of actual damages in this sort of situation, then I would argue that your law is broken. Clearly those damages can not exceed the full cost of the original plan plus any actual costs of dealing with the early transfer, so a bill for 100+ bucks is just a shakedown, pure and simple.
