Telkom Unable To Resolve Problems

I have a business package with Telkom, which includes telephone, ADSL line and a data package. I have had this package since January 2015. The bundle was meant to include 10gb of data per month, but Telkom erroneously signed me up for an uncapped data package, Being unaware of this, and needing more than 10gb of data per month (which is what I thought Telkom were supplying) I signed up for an uncapped bundle from MWeb, which I have been using until 31 May 2015. When I became aware that I had uncapped from Telkom, I cancelled my MWeb subscription. Now my Telkom data is not being provided, and Telkom can't seem to pick up that they are the service provider. After numerous calls to their \helpline"I still cannot get an answer from them as to what the problem is - with different call centre assistants giving me a different story each time."""
