Connectivity

My internet went out yesterday. It happened before.  I went online talked to an agent fixed in about 10 mins.    That's the usual.  Yesterday I terminated my service.  I went online the agent said I had to upgrade my plan so it could work.  They upgraded it then disconnected but didn't restore service.  I went back online and that agent tried to sell me a phone. Still no service  over 2 hours.   I called now I just wanna cancel the service.  That agent ignored me and still tried to fix it.    He didn't.   He said he had to connect me to the tech department.  WHO WAS HE.   He sent me back to the waiting line.    I had to keep calling back just to cancel. 2 more hours.   As a last resort I tried to buy the wifi pass.    One agent said 8 have to have xfinity mobile or it won't work. Another forced sales tactic.  Another agent says i can't use them unless I have an account.   After I told him repeatedly I have an account.  He just wanted yo offer me sale packages.  Why are you goin so hard to sell stuff when I was already a customer.     So now I just can't use xfinity at all because you are in your own way
