Emails are ignored

I have been emailing revline for 3 months now, since i relocated and the emails are ignored. The billing address is INCORRECT!!! I am having problems trying to show proof of residence! The call centre number is UNANSWERED! I need to know about my bill as I am not being charged for certain services! NOBODY ANSWERS THE PHONE AND REPLIES TO EMAILS! but let you owe them money, see how fast they contact you! pathetic!
