In Home Expert - traded in phones, but not received credit
Last August an in home expert came to our home when we were being converted to fiber and sold us on switching from Verizon to ATT. Part of the sale was a $20 credit per month for trading in our phones. The expert did not process our trade in correctly and no one can find the phones. Per discussions with the 800# a credit was issued for one of our phones but to a name I do not know.
I have provided the IMEI numbers of our old phones and no one can find them. I have called the 800# several times and been told the in home expert has to solve. I have left many messages for her and her supervisor and no one is getting back to me with a resolution. I have their contact info. The corporate store manager has been helpful but he can't solve.
Who can I escalate this to get resolution. I traded in 4 phones and was to receive a credit of $2,800 in total, but have not received it.
Very frustrating!!!! I need help! Any suggestions?
