Telkom is *****ing my money

I had a Telkom wi-fi contract which i stopped 2 months ago already. I contact them to ensure that it was stopped and of cause they did not. After phoning them and making a case they ensure me it will be corrected. Today once again they subtract the money from my account. This is theft. I think they are the worst service prokureurs ever. Never use them, they are *****s. Now i know its going to be a struggle to get my money back
