I am NOT a Comcast employee. Just a disgruntled customer for many years!

@XfinitySara​ It is the Xfinity App. 
I believe the SN and MAC address were entered improperly when I was at your store because I am using my own router/modem combo. 

Thanks for confirming those details! We would be happy to take a look on our end to ensure we have everything listed correctly.

I am the disgruntled long time client and don’t believe my language was remotely inflammatory to be deleted by Comcast. With as many times I have had to contact you regarding your service interruptions,  price increases and lies from some of your “expert customer service agents” my language is subtle in view of the deceit handed me on so many occasions. I keep a complete record of all my contacts with Comcast including agent names, location, date and conversations . I have a notebook with all these records which are numerous and do you think I should recommend Comcast to anyone? Do you want other clients to see my review here? Probably not and you consider my language to be a problem, how about your problematic service, hmmm? Fe better about my language now, do you?
