Phone line hacked $1000 in international calls made - kicker is the phone line was never used!!!

Received June 2019 bill from Xfinity that included international calls totaling $964.88 on phone line.  HOWEVER, the phone line included with the Xfinity package has never been used.  No physical phone ever connected.  No mobile phone ever connected to it.  Only included in package to get better monthly pricing.

 

READ MY TEXT - no physical or mobile phone was ever associated/connected to the Xfinity phone line/number.   No call forwarding, voice messaging or other services ever set up. BECAUSE THE LINE WAS NOT IN USE!

 

The calls made were to sequential phone numbers in Great Britain and numerous calls were placed at the same time over a day.  As soon as one ended another was placed.  

 

Additionally, call log showed lots of other calls being answered and missed since service was installed.  The account had two phone numbers added after talking to customer service as associated phone numbers - no idea whose phone numbers these were.

 

Placed numerous calls to Customer Service, billing, etc. for over two weeks.  Never was allowed to talk to a supervisor.  Had to explain the problem over ten times to customer service reps who passed me around and promised supervisor callbacks.  A supervisor never called me back.

 

Spent HOURS on the phone with Customer Service begging for a resolution.  Talked to three or four different people each time I called.  

 

It it has been almost three weeks since I first reported the problem and I still have $964.88 on multiple international calls all made on same day at the same time on my XFinity bill.

 

So here I sit in my second hour on hold waiting for yet another transfer to another department....
