Fraud and scam from xfinity mobile and executive resolutions refused to help

I had tried signing up for new service online since they had a good promotion that after checking imei of old phones I was eligible to get a free trade ins for iphone 16 and iphone 16 pro.  After submitting order online I never received a confirmation email, and so I just tried to submit the order again, and again no confirmation was sent. So Finally fed up with the service online their website I went into the store to get this plan set up. When I went into the store I was told that the promotions I have submitting orders for has ended that same day and so they would have to call to get them added. After waiting about an hour the store associate came and said that she is having issues getting it but if I would like she can give me a different promotion. This new promotion was to give me $600 off one phone and $350 off the other with trade in, but the kicker was I was told (BY THE STORE MANAGER) that I would also receive $500 in bill credits towards my future bills FOR EACH LINE! I left the store paying over $300 and that was to cover first bill and set up fees. Now about a month later my bill comes out and I find that what I was told in store was a lie and that I am getting no credits and everything told to me was deceitful tactics to get me to sign up. I write in to the corporate with a complaint and spoke with a woman named Amy out of Denver who handles BBB complaints. Amy was completely unhelpful and did not seem to care at all about what I was dealing with at Xfinity. Given I have been a gold status customer for 4 years I did not expect this his. She basically gave me the middle finger and said that she will not help me get this situation straightened out. She said she does not care that her associates lied to me and does not care about the system issues I had getting the order submitted initially and that she refuses to help me with this. I work full time and finding time to deal with this has been a nightmare, and I just don’t want anyone else to get deceived.
