No service from Telkom and still I have to pay!!!

After reporting our landline several times about our modem and the internet not working - still no service. My husband was forced to get m web for the data just to be able to use the internet at home. I have send an e-mail tot Klerksdorp. Asking for a report about when we stopped using the data. No response. I asked them to cancel the data and everything else except the adsl line. No response. I asked them to activate a debit order for payments. NO SURPRISE!! This they actually did. It was all on the same e-mail. HELP. If I dont pay - they cut the service? At this moment we cant use the telephone. Again something wrong with the line?
