NO SERVICE FROM AXXESS BUT I MUST STILL PAY

My ADSL line has been down since 23rd Aug. My ISP is Axxess who should be managing this line which I pay them for. I am now told they don't have any idea when Telkom (Openserv) will restore the line, if at all. So I have asked them for a refund to the payment I made for my Sept service and asked them to not bill me for Oct, they say they can't stop billing me for the service (I am NOT) receiving and can only request a refund when Openserv restores the line... WHAT!!! So I must just pay for a service indefinitely they are not supplying until its fixed which might never happen!! Not to mention the amount of money I am forking out now to get internet access for my business!! DISGUSTING really.
