No service from Telkom

I have had a faulty line since the 15th of February , technicians have been sent out and still there has been no progress, no feedback, no internet! And now I receive my bill which indicates that I must pay unnecessary call out fees! This is ridiculous as my internet is not fixed. I do not believe that I should even be paying for this service as I have no internet. I have tried to cancel my service with Telkom as of immediate effect and have not received any feedback from Telkom . I do not wish to use this service anymore and I do not wish to pay these fees
