Bad service from Telkom

Good day, This is now my 3rd Complaint against Telkom, the first two I haven't received any response from Telkom. I made some phone calls, emails, live chats on Telkom's website and I just can't get any further. I have cancelled my data contract on the day after I received the router as there are no connection where I'm working on site. That was on 16/17 November 2018. I received a cancellation reference number: ********** 8, cell number: ********** 347. Telkom need to arrange that they collect it from me to get it cancelled on their side so I can be refunded for the 2 months the payment went off already. I need to get this resolved asap
