Botched Android Phone Upgrades Due to Unqualified Store Personnel

I want to express deep concern that the employees at the XFinity store in Glen Allen, Virginia are not properly trained. They have fouled up 2 Android phone upgrades in 6 weeks. I upgraded to a Google Pixel 10a from Pixel 7 but the IMEI's got mixed up with my husband's upgraded phone and several trips to the store and calls to Mobile support did not resolve the issue. I then was upgraded to a Samsung 26FE but the store agent did not use the correct transfer program so I lost ALL text messages from the transfer date and before. I had tons of information in many text messages and all is lost. I was devastated and another trip to the store and hours of research yielded no was to retrieve those text messages. I cannot believe the store personnel are not properly trained and lack basic knowledge to properly upgrade mobile phones. I am thoroughly disappointed in Xfinity and have been a customer for 27+ years. What is being done to get staff better trained?
