Worst Service Ever! Unresolved billing since FEB!

I requested to close my Telkom Mobile account in February 2015, i was told i have to serve on month notice which would have been March. Also highlighting that the 24 month contract period was expired in January 2015. I am still billed to this day, money is being debited from my account even in July. And this is after making many calls trying to resolve the issue. To make matters worse, when i called again to follow up, i was told my account has been suspended because i didn't make payment! REALLY!!! I'm glad I don't have to be stuck with such a company for any longer, I just need to be credited for all the incorrect debits they took from my account and just cut all ties I have with the company. Someone please help. My case number is ***6
