Xfinity Failed - Switch from ATT to Xfinity

I spent a total of 5 hours working with Xfinity, first online with customer support, then 2nd tier, then in the store (Evergreen, San Jose Branch) trying to switch my provider from ATT to Xfinity. ATT provided the code to unlock the phone, so the number could be switched to Xfinity; this is where the trouble started. The technician was clealy not experienced enough to help with this process. He was kind, patient and understanding. I was told to go into the store, which I did, but they were unable to assist me. I was told to go to ATT to help unlock the phone, ATT (two branches) was unable to unlock the phone. I went back to the Evergreen Store, and out of pure frustration, I purchased a new phone. I had to get a new number. I know this is not the end of the world and very important and serious issues are taking place. However, I now have a $1300.00 Galaxy Fold that is useless to me. I feel cheated. Xfinity needs to fix this satisfactorily for me, before I escalate it to legal level. How can you fix this. NO, I don't want a watch, I have three already. Financial or service discount are the only acceptable options.
