How do I stop Xfinity from spam calling me
I left Xfinity years ago when I moved. My old roommate lost the xfinity equipment while he moved out. I looked at the xfinity bill when they called me a while back and paid for the missing equipment. I still get calls from them saying to return the equipment. I already paid the bill. Anybody have suggestions on how to have them stop calling before a make a BBB complaint?
