Bad customer service - Rain ISP

Still waiting on feedback on my queries. There was ***** on my account and I was promised a call back over 2 weeks ago. Basically my ex husband locked me out of the account and changed the name to his but it is still connected to my ID number and the account is now in arrears. I did try to disconnectbthe service in August last year and was told it is no longer in my name and that they cannot assist me. They didn't inform me that my id number is still associated with the account. When I tried to renew the service 2 weeks ago I was informed if the arrears.
