What is up with your customer service?

I am now on my 6th representative. I called three days ago to have my cable turned off. I want to keep the interent. I spoke on the phone to have that processed. Three days later I still have the cable turned on. I am now in and endless cycle of being pushed from one representative to another. No one has answered my question about when the cable will be turned off. What makes this so frustrating is that now they are under the impression that I have an issue with my internet? What is going on? If I had cable+internet and I want to subtract the cable part of that equation, why does it take 7 representatives to answer a question. Any why do they suddenly think I need new interent equipment. I am seriously considering Starlink at this point. No wonder everyone is cutting the chord.

Also, why did I receive 27 text messages during the time that I was on the chat? Any why 9 emails from Xfinity asking me to verify my identity and providing me "Here's the article you requested?"

UPDATE: As if to add insult to injury, I was charged again for the service I wanted to stop - Cable. When I first called I told the representative I wanted to drop cable and keep interent. I signed up for the 800mbps plan and was told if I signed up for auto pay, the cost would only be $88. Ok, I signed up. Well, I got an email today telling me that my auto pay went through successfully for $249 or so. What makes this even worse is that I had already set up a payment through my bank for my bill that was due. Argh.

What do I have to do to drop cable and keep internet?
