Cancel Service or Account How to

My daughter just moved from her apt and is temporarily living w me. We paused services for couple of months but she still has not found a new job/place. I just got billed!! The customer service rep was not to kind and didn't offer any assistance other than you have to pay the bill.  How do I cancel account then so I dont keep getting billed. Can I renew it in the future?

Please help me!
