Telkom very bad service

I have app**** for the Telekom 10-10 gb wifi deal at Hifi Corporation and while I was still waiting for Telkom's response I decided to cancel my application before it was even approved. I then app**** for the 40-40 gb wifi deal and it was approved and I received my package from Hifi Corporation. Telekom deducted an amount of R229-00 but later suspended my account saying it is because of non payment. Through enquiries I found that the first application (10-10 gb) was never canceled by Telekom even though Hifi Corporation already canceled it and they got a reference number for the cancelation from Telekom. Telekom and Hifi Corporation both cannot find the exact problem and I'm still not able to receive and use my data because of the suspension. I never received the 10-10 gb deal but I am billed for it. This is not my fault if the cancelation was properly done and I am really afraid of being blacklisted for non payments. I need this matter to be resolved and my name to be cleared from any blacklisting.
