I have mail you a payment

Moved to Customer Service as this is not Guidelines related.

@user_s7lngl 

I have mailed you a payment a week ago to your 918 North Arthur Ashe boulevard here in Richmond Virginia

Is this the address on your billing statement?  You should send all your payments to the address on your billing statement otherwise Comcast billing may not ever receive that payment.

Hi user_s7lngl, thank you for visiting our Forum community and sharing your payment concern. I can research your account to confirm if that's been received. To confirm, you mailed your payment to a local Xfinity store?
