Telkom’s mobiles horrific customer service

I have had a mobile contract with Telkom for over 2 years, early July I opened up a second line. End July I receive my bill and see R200 worth of UK smses at all hours for a period of around 2 weeks. I query this immediately (on the 5th Aug), try call the number and it says the number does not exist, so I have been charged for smses I didn’t send to a non existent number. I get a case number and am told it would be resolved in 72hrs. Weeks later still no feedback so I call again and am told it’s with the relevant department and they can’t follow up with them, I must just wait until they get hold of me. Some more time passes and no feedback so I call again. I speak to a very friendly and helpful gentleman who speaks to his manager and says someone would get back to me within 24hrs and I received a new case number. It’s now almost another two weeks later and STILL NO RESPONSE. I’m totally and utterly blown away by this whole process and lack of service. Really disgusting!!
