Hello, Lepegeorg! Welcome to the Xfinity Forums.
I'm sorry to hear you've been having trouble getting ahold of an agent to help you, but you came to the right place!
I'd be more than happy to work with you to make any necessary corrections to your account, as well as figure out where the purchase came from so we can avoid it happening in the future. Please send me a private message with your first and last name, as well as your service address so I can assist.
