You lost me today, Xfinity

After 4 days of relentlessly trying to get my issues figures out and fixed, and dealing with numerous chats, bots, texts, emails, etc., I tried to deal with my issues in person at the Bolingbrook, IL Xfinity physical store.  That was a mistake.  But first, to the beginning of my issues.  And by the way, I'm a 10+ years customer that has been paying $350/month to Comcast.  Ever since there were "improvements" made by Xfinity on May 11 in my area and we were without service for the entire day, everything got worse for me.  Our TV was pixelating wildly on all channels and the wifi reception got much worse.  A week later, we finally got a technician to our house, who ended up having to put a new box on the outside of our house and he strung a new cable diagonally across the middle of our backyard to the utility box out back.  Incidentally, that cable is still not buried 3.5 weeks later.  The TV reception got better after that, but not the wifi coverage.  Then our wifi extender pod stopped working.  That took me several hours of texting and calling to get someone to finally let me know that it was no longer functional.  I had been given that pod by Xfinity a few years ago because of the poor coverage in our house.  At no cost.  Now, after lots of back and forth with various entities within the Comcast umbrella, I was promised a replacement pod over the phone.  They said to take the old one into my local store and it would be replaced - they even put a note in my file to direct the staff at the store to replace it for me.  They also agreed that I should receive a second pod to adequately cover my house.  Now at the store earlier today, I was told by the person helping me that they couldn't exchange the pod for me there - they only had pods to sell.  This was frustrating, but whatever - as long as I could get them in a reasonable time, I'd be happy.  He told me that I could get them by tomorrow most likely.  Then, he brings me over to a video station on the wall, where I need to have a video chat with another person to confirm something or other.  Weird, as I'm in a Xfinity store in person, but okay.  Then, after talking to that person on the screen for several minutes, he says that I will be called on my cell phone "in 7 minutes" to confirm more stuff with someone else.  This is now starting to get bafflingly odd.  I stayed in the store as I wanted to make sure this got fully resolved before I left.  My phone finally rang, and a woman says hello to me and asks me the reason for my call.  [Edited: "Language"]?  After I get her to look in my file, she goes through a series of putting me on hold repeatedly.  As I'm literally 25 minutes into the call and on hold for the 4th time, an employee came over to see if I was being taken care of.  I said "sort of" and started explaining my issues to him.  A female named "Carolina" then came over and he introduced her as his manager.  While I was explaining things, she just got up and walked away.  Strange, and a horrible look for anyone in the customer service world.  Then the phone lady finally came back, and started talking about how I'd be charged for one of the pods (with one being given to me as a replacement for the broken one).  This was the last straw for me.  I hung up with her, told the guy sitting in front of me that if I could not be given 2 wifi extender pods at no cost by the end of the day tomorrow, Comcast/Xfinity was going to lose me as a customer forever.  He shrugged, so I got up and left.  Bottom Line - Comcast/Xfinity is losing a 10+ year, $350/month customer because they would not give me 1 extra pod to get proper wifi coverage in my house, after the service became worse following "improvements" made by Comcast in my area.  [Edited: "Inflammatory"].  As soon as I have arranged replacement services, Adios!
