Hello Speedy9 and thank you for using the Forums for your question. You can disconnect your service and return your equipment at your local Xfinity Store. I would be happy to look the address up for you from here if you would like. Please send me a private message verifying your full name exactly as it's listed on the billing statement? To send a private message click on my name, then click "Send a message".
Thank you, thank you, thank you Nerdburg. I have spent many hours trying to find that information. I guess I should have asked you first ;>)
Speedy9 -- I'm happy to hear that Nerdburg was able to help you, was there anything else you needed assistance with?
