Xfinity Internet ESCALATION!

Since mid-October I have been dealing with a situation where my devices will suddenly stop connecting to wifi (smart TV, laptop, mobile).  I ultimately have to contact Xfinity customer service and they will send a "fresh" signal.  Many times that fixes the situation but only for a couple of days and then the same issue occurs again.  This has happened 6+ times.  Xfinity has sent out two separate techs to my home and they say they say they solved the issue yet it STILL occurs.  It is unacceptable that this issue has been going on for months now and has not been resolved.  Your live agents apparently do not know how to read the history of issues on my account as they ask questions that they should be aware of and or simply say that they will send a tech out.  After a recent call, I got an email from Xfinity stating that my main number was disassociated with my Xfinity ID and proceeded to receive 22 (yes, TWENTY-TWO) emails from Xfinity saying "Here's the article you requested"....I requested no such articles.  

1. I need actual support to resolve my internet issue.  It is not sustainable for me to get in contact with Xfinity every couple of days to get a "fresh" signal sent.  

2. Please train your customer service team better, they have been absolutely worthless and getting my issue resolved and/or escalated.
