Unhappy with service

In Jan 2016, I contacted Telkom to say that there is something wrong with our home line. We didn't do anything to the phone, one would understand if we have moved or something like that. I contacted the call centre and logged a call for help. Had to contact Telkom myself several times to enquire what my status is of the call.Eventually when I threatened to take it further, I was contacted by a gentleman who rudely and abruptly asked me what the problem was. I told him that if I knew; would tell him . I asked several times if I would be billed and I was told, not all all... NOW on my monthly bill, I'm charged R239 FOR AN UNNECESSARY CALL OUT. I mean;are you kidding me. Telkom thinks because they hold the majority share of the market, they can treat customers the way they want to.... I would appreciate it if Telkom do their homework and NOT charged this ridiculous fee for an unnecessary call out which by the way I pay them a fee every month to assist when I have problems.
