Complaint about service

I'm sick of your non existent customer service in chat and on the phone. For months I've been dealing with a terrible phone from you and lousy phone service. I thought I may need to upgrade to get anything descent because I was in prepaid Now Mobile and internet essentials. I wasn't approved for an upgraded phone however after that I started getting billed for an internet upgrade I never even received. I hate your chat support. I have spent days upon days and too many hours in chat being transferred all the time and no one listens to my concerns. They treat no one with respect. I would never  have Xfinity again . After the way I been treated. And I want a refund for my phone bills and internet. Because I've had the nothing but miserable service and a phone that is lousy and no help from anyone . I'm done. You owe me I don't owe you a thing . You have wasted all of my time and not you never addressed any of my issues time and time again. You can forget about me paying anymore. I want a full refund for a worthless phone and worthless service.
