Kind of a Theft by Deception.

In August of 2022, I saw the promo for a $1000 trade-in for preordering a Samsung 4 Flip or Samsung 4 Fold. My wife and I went to the local AT&T store to check on the promo. The store assistant said both of our phones (Samsung 9+) qualified and we could keep our plan and we also get free phone cases.  So we ordered the phones a Flip 4 and a Fold 4. Once we placed the order the assistant said they did not have the cases in the store and we would need to go online to get them. I went online and through a chat session I was told we could only get them if we order online, I went back to the store and canceled the order then went online and order the phones with a $1000 rebate on both phones plus free cases. The website never indicated I did not qualify for the promo. The phones arrived I shipped the S9+'s to AT&T. They received and processed the phones. I have waited for 4 months to start seeing the credit on my bill, but no credit to this date. I go online and through a chat session they say I don't qualify. I asked to speak to a supervisor all he did was what looked like copy and paste the same answer. I requested many times to talk on the phone because it is easier for me than trying to type. Finally, they said they would call me in 5 - 10 minutes they never did. I'm just trying to resolve this but they will not talk and they have my two phones (theft). I will be contacting my state's Attorney General Consumer Protection Division if AT&T does not make voice contact with me. Has anyone else had this type of problem?
