Trade in issue

I purchased two new phones with trade in over the phone back in December of 2024. I also got a new phone and line for my child. I was told it could take weeks to process shipping information to return old phones. I called in January to activate new phones and told them still haven’t received information to return old phones. I called many times and was told the same thing. I went into the store and a gentleman helped me went into my account and he said everything was all messed up about the trade ins. It showed ticket was canceled I created as well  so he created a new for me. Nothing was resolved after and they cancelled the ticket # again. I contacted corporate and created a case number. Tina called me back basically told me it was my fault and I only had 30 days to return my old phones and basically told me I was a liar and I didn’t call until like 3 months later which is false information. I told her how can I return my phones if I’ve never received an email.  I also called many many times about this. I’m a longtime customer and feel disrespected that I am being treated this way.
