I purchased a new S25FE and it's defective (will not activate 15 days) and they will not accept for replacement?

I've been a customer for 25 years and I went into a xfinity store and purchased a new phone. Spent 3 hours in store and it would not activate. Took it home and spent another 14 hours and two days on phone with 12 different people and mobile phone advanced support. I took phone back to store I purchased from and they would not give me a receipt for phone being in their possession nor give me a new phone to replace this defective one.

I ended up opening a Dispute with Chase bank and they cancelled the $700 payment after reviewing my documentation, screen shots, and text messages .

All I wanted was for xfinity to give me a new working phone and take back this defective one that would not activate. I can see why over 200,000 people have left xfinity in 2025 due to lack of customer service.
