do not have service with comcast

I was scammed by SupportSquad when I bought a new TV. Somehow they got my debit card number & started charging me $9.99 a month. I immediately called my bank & was advised to cancel that debit card & have a new one issued. I personally went to the bank & cancelled the card. I decided to call Support Squad after returning home only to be advised that I had authorized this service when I hadn't authorized anything. After arguing with the CSR I demanded this service be cancelled & send me an email confirming that service was cancelled. They said they couldn't do that. They weren't authorized to send out any emails. Huh? I then asked for a manager (who never did come on the line) & was given a "confirmation" number that service was cancelled. I then emailed Support Squad & sent a copy of the email to my bank also. This a a clear example of fraud & advise everyone who's had any electronic purchases recently check their bank statements.
