I have been a Comcast customer for 2 whole weeks now. I am making my last attempt to get the service to work on the X1 box. Today was my third visit to the store (that is an hour away)changing out equipment that customer service has been unable to activate. I’ve spent countless hours on the phone with customer service only to keep receiving the same XRE-00251 error code. Has anyone had any luck having this issue resolved? I think that I’ve decided that if they don’t fix it tonight, I should return all their equipment and find a more reliable service provider.
