No service but continued to be billed each month

I logged a fault with Telkom. I had no service on my landline. A reference number was generated but absolutely nothing was done to address my problem. Each time I went online to track the status of my logged fault I'd be met with it was on step 2 of 4. For a whole month! Telkom allows you to log many faults and new reference numbers are generated but absolutely nothing is done to fix the fault. Yet each month the bill timeously arrives. Telkom expects payment for no service. Seriously!!!! The customer service is pathetic and I am utterly disgusted by Telkoms prolonged failure to restore a service I'm being billed for but unable to use.
