Customer NO SERVICE!!!

Ordered two phones, October 8. One received and the other not received. Empty FedEx box on October 17. Nearly 22 hours of phone calls, spoken to 12 different representatives, visited Xfinity retail store at their direction four times, and have tried to get Xfinity to correct a change so-called support made to my wife’s phone line. 
in addition, phone service has been changed and we are going to be billed for service on a phone we never received.

had to file an FCC complaint to get any minor fixes to my mobile account. 
Customer service, people courteous, but don’t seem to understand clear English and cannot implement or conduct corrective changes to my account.

There appears to be no ability to communicate with anybody who has any more authority than just to answer the phone.
