Nonstop glitching

@XfinityJon​ Hi - I have done all of the normal restarting of the cable box, checking the input, checking my wires (many, many times because I can't get through the automated system without agreeing to do the things!!) & everything seems ok.  I actually did work with someone via text & she told me that she was taking care of everything - escalating my concerns and giving me a credit.  But the TV is still messed up.  It's on & "watchable" but it cuts out/pixelates every 5 minutes or so.  So, as I reflect on my customer service experience, I realize that I still have no idea what's happening as far as a fix.  A credit is nice, but I have a senior in the house whose main source of entertainment is that TV and the dumb thing cuts out at crucial moments of her shows.  Very annoying.  Also very annoying because I've spent hours on this already & feel like there's no resolution.  I doubt the credit I'm being given is anywhere close to the hourly rate I would charge for working, and dealing with Xfinity 100% feels like work to me.  Like I expressed to the agent, the TV has been cutting out for weeks & it took me this long to deal with it because trying to get anything done with Xfinity is exhausting.  I have a bad feeling that I am going to end up at an Xfinity location to deal with this issue.  And I literally do not have time for that & it shouldn't come down to that.  But it does, EVERY SINGLE TIME.
