Poor customer service

On December 1, 2023, I called Xfinity to restore my Internet service. I spoke to agent and she told me that I could pay $100 and pay the rest of my next bill and my service will be restored see as well get my bill lowered to deals, I paid $100 my service was on the next day December 2 in the morning my service is off again I called Xfinity. They worked on it for two hours and then restored my service and for my inconvenience gave me a credit the next day today December 3 my service is off again and I called his Finity and I got the runaround  And I treated very poorly by supervisor telling me that I have to pay $75. The money that the lady told me that I would be able to pay my next pay cycle. Did I have to pay that or I won’t get my service on even though Xfinity, amid it to be a wrong day before, for turning my service off because it agreement we had  Now the supervisor hung up the phone on me and told me that I need to pay my bills even though I talked to somebody on Friday who agreed that I had to take $100 and I can pay the rest on my next bill and I was telling me that there’s nothing they can do and I can’t get my service on  When I paid the hundred dollars and it’s all I had that’s the reason why I told the lady said it would be perfectly fine now I have no Wi-Fi to do none of my work and my kids can’t do school  school work
