Never trust any operators from comcast, each one tells you something different each time you call.
They do any thin to take people money.
After I paid my bill, comcast suspended my service twice, when I called, they wanted to charge me for reconnect my service, Charge me each time they reconnect the service, After I got mad the operator said, she will not charge me for reconnect the service, I hope so, I do not trust Comcast.

I cancelled Comcast. Their prices just get higher every year. It is not a good investment for my family's welfare funds.

I just purchased an apartment a couple months ago. Apparently the tenet that lived there had cable with Comcast and never paid. My new tenant that moved in wanted cable and decided to call Comcast because they work that area. But they are denying my tenant service because apparently the property owner is responsible for paying the fee that belongs to someone else. Now they want to charge me like $500 for something
I never owed to begin with. Please advise.

Better read the service contract from your previous owner. Apartment contracts are different from individual home service. Most apartment or condo complexes have restricted access, which means they have a contract with ONE provider and no tenant can use another cable or phone service but the one contracted. With that contract, the building owner assumes liability for any unpaid debts. If you took over the contract with the sale of the units, then you are stuck. If not, then renegotiate it.
