Telkom *****ing Money

I phoned telkom to give 30 days notice for my LTE cancellation. They go an cancel my line IMMEDIATELY!. I then phone telkom to find out why the hell they did that. They apologise and let me know that because of the mistake they made they will not bill me at the end of the month. Guess what, The F&$*%rs bill me.!!! Now they say i have to pay. I now have to pay for a service i did not have. *** is going on. How can they bill you for something that does not exist. It was their mistake and now i have to pay for it. This is ridiculous. Fix this **** Telkom.
