xfinity/target promotion

I received a voicemail about xfinity/target promotion about saving 50% of my entire bill until June. It’s very shameful that I fell for it. Does xfinity have data bridge that they’re unaware of? They had all my account information. They brought my balance to $0. They knew my name, phone #, address. Does xfinity even care? Maybe it’s time to move on. Because my service provider couldn’t not protect data. If they are able to mirror my account and act like they xfinity costumer service what else do they have? My card info! Big companies like xfinity are always lazy and careless protecting their customers. From what I can see online, this scam has been going on for a while and they haven’t done anything about it. It soooo shameful and careless of you xfinity.
