Trade In Scam

I am waiting to receive the remaining credits for a trade in.  I traded in a device back in 2024 for a promotion.  I was supposed to receive a credit for $1000.  After 4 months of waiting I was told the trade in wasn’t received.  I had tracking info showing the phone was delivered to the facility it was supposed to be delivered to.  I was on the phone for about an hour and was told I would receive the credit of $41.66 monthly but I would have to call it in every month!  Well, as inconvenient this is, I did it because who wants to be out of $1000?  I called in for my November (last month) credit and was told they have reached the amount of credits they can give and that it has to be escalated for approval.  I was promised I would see the credit in a couple of hours.  That didn’t happen.  I called again and was told the same thing.  Again, no credit!  I was told the ticked was processed.  I talked to an agent once again who told me to go into the local store to get this issues resolved and they would note the account.  I took the advice and went into the store.  I explained the situation to a rep whose name is Clay.  He looked at the account and said the ticked was denied and there is nothing he could do.  I told him I think it’s time to get an attorney involved, he walked away, came back and said since your talking lawyers I can no longer help you!  I asked once again of giving me the credit and making this right.  He said again, I can’t help you.  So I guess it’s time to lawyer up.  I am soo tired of being given the run around by this company!  They need to make this right!
