When I wanted to add my gmail account, it wouldn't let me saying that the address was associated with another account. I had an xfinity account three years ago, but cancelled it right after starting it. Im sure that's the one it's referring to. How do I the to cancel my old account so I can use my current gmail account for billing, etc.?
@wmartin926 please PM me the gmail email address so i can investigate this for you.
