I give you my word ... your complaint will go unanswered!

I’ve been with T-Mobile since Ben Franklin was a boy.

Was conned into trading up to a new iphone and was told if I sent in my existing phone, I'd get FULL CREDIT for the new iPhone on my bill.  Long story short - they got my phone but credit for the new phone nunca happened.

Five months and countless hours on hold (my time is worthless, right?) to call centers around the world. I cannot even connect w/ my 'local team of experts'. And the result is a partial credit 'each time I call' w/ the assurance … "I give you my word I will fix this." 

Nada.  Crickets.  Bupkis.

It goes to say that after  being place on hold for hours, numerous supervisors have promised to escalate the problem and they assure me they will return my call in less than two weeks. 

I don’t see how to resolve this, and all I smell here is FRAUD.
