ATT can't find my trade in phone!!!!!
My family and I have been ATT customers for 25 years. We have been happy until I upgraded my phone with a trade in at an ATT store. I did not keep my paperwork as I assumed that my info would be stored on my account. The store mailed back my trade in phone but ATT has no record of receiving the phone. The store told me they do not keep any paperwork beyond 3 days and ATT Corporate has no paperwork. What can I do? No one is any help!! Thank you!
