Xfinity Customers BE WARNED!!!

I've been trying to fix a fraudulent billing issue for 9 months and not only has it not been resolved, they not only disconnected my service after promising it would be resolved, but also added more charges.

My experience with CUSTOMER NO-SERVICE after more than 10 years of being a customer:

• CHAT: The chat reps can't do anything but give you runaround and waste your time telling you they can help but do nothing. BTW you will be disconnected and reconnected with another representative about 4 times during any chat conversation and have to start over explaining everything even though they say they're looking at your account. Apparently they don't keep chat records. They gave me the FULL ADDRESS and NAME of another customer after I gave them my name and address. How does that make you feel about your own privacy and security?
• PHONE: ROBOTS ONLY, impossible to reach a human 
• STORE: SALES ONLY - ZERO SERVICE: No sense in talking to a human because they can't do anything to fix a messed up bill. They tell me to call the regular number and say "disconnect" to get a human (btw that doesn't work - still only robots). 
• FRAUD DEPT: REACHED A HUMAN, BUT... spent over an hour on phone to be transferred twice then transferred to billing. Had to explain things multiple times. They removed partial charge, but refused to removed older charges because they were older than 6 months, despite 8 months of chats, store visit, and phone calls on my part trying to resolve it. More incorrect charges still added to next billing cycle.
• FRAUD DEPT 2nd Call: I was assured my bill would be fixed. Instead I received a DISCONNECTED notice and $250 more charges for "unreturned equipment" and late fees.
