Telkom-Tconnect ****?

I received a call from Melissa Naidoo who said she was from Telkom and offered to upgrade my current 2Mbps connection to a 4Mbps connection for approximately the same as my current monthly subscription. As I had wanted to upgrade I gave her my details including bank details to set up a debit order. She then later said that she worked for Tconnect the subscription arm of Telkom and gave me two numbers a customer care number ***and the Telkom number 10210. The debit orders were to commence once my upgrade had been carried out with a new modem and cabling - having found out the truth I do not wish and will not permit an upgrade to commence though Tcomnnect. I didn't query or think about this during the telephone call but afterwards realised it seemed strange that Telkom should use an 0861 number so I looked up Tconnect to discover that the main internet coverage is people questioning whether this is a **** and a website which gives only this customer care number and an "info" email contact - they are obviously not an official arm of Telkom as I was told. I phoned Tconnect and told them to cancel my order, but I could not receive immediate confirmation of cancellation. The customer care lady Numpilo said that she would pass the cancellation to the relevant department who would send me notice of confirmation of cancellation. Are Telkom aware that Tconnect are doing this and if so why do Telkom continue to let an unconnected company pass themselves off as Telkom?
