Billed for unused Services for three months

Below are the emails which I have sent to Telkom till Today they have not rectified their error and my invoice is sitting at a whooping R2200 for services I haven't used --- ---I refer to the below mentioned email which I have not been furnished with a response on. Apparently my services have been discontinue due to non payment. please provide me with contact details for your legal or complaints department, I am currently busy with exams I am not in a position to be without internet, I have contacted Telkom countless times and even sent the below email but this matter since hasn't been attended to. i Good Day I app**** for an upgrade from a 2Mbps to 10Mbps at a Telkom store in Eastgate mid August 2017, I was assisted by Sithe. He advised that the upgrade comes with a router, 10Mbps and uncapped internet. I also made him aware of my current internet provider which is MWEB. He said Telkom will contact me once the application has been approved and a technician will be dispatched to my premises, this will give me sufficient time to cancel my internet service with MWEB. On the 4 of September 2017, I went to the branch to follow up about my application. Sithe (Telkom Consultant) advised that my application was declined as the system indicates that I have an outstanding amount of R675 with Telkom. I disputed this and I provided him with proof of payment on the 5 of September 2017 via his work email address. On the 27 of September 2017 I received an sms advising that my Telkom account is in arreas, I thereafter checked my emailed statement which reflected that I have been on a 10Mbps line from 18 August 2017. This was not communicated to me I was still waiting for feedback regarding the outstanding R675, and communication about a technician or collection of a router login details for my Telkom internet account. I called Telkom on the 27 of September 2017, I was provided with reference number ********** 4, trying to find out about this statement. the Agent said they will call me back within three working days. There was no communication from Telkom after 3 working days again I called on the fourth day. Today is the 7th day since I logged a query with Telkom I haven't been provided with any solid feedback on this issue, other than the sms advising that my account is in arreas. I requested to be contacted via email or sms as Telkom always claims that their calls are recorded but I have requested for recording till today I am still waiting for it. I am not sure if I can get the recording of the 27th of September where I was advised that I will receive feedback within three working days. I have had my issue with Telkom before, but this is really beyond, I would like my statement to be updated accordingly. for a 2mbps line, I would like to have communication regarding application for an upgrade, router internet account settings. Once this is done I can be billed for an upgrade depending when you decide to attend to this matter I would like to cancel my current internet service which is currently on a 2mbps line so that I can move to Telkom.
