No customer service!!!

I was approached by Sell Direct ***)to upgrade my contract with Telkom on the 29.09.2015. They said I have a 5 day cooling off period. I tried to contact this company on the 30.09.2015 and 01.10.2015 in order to cancel this upgrade before they deliver the product. Then they will try and force delivery charges,etc. on me.<br> <br> I have contacted Telkom via e-mail and they were very prompt in their response that they are sorry for the inconvenience but they can't assist. <br> <br> How does Telkom allow such a company to market upgrades on their behalf and then tells the customer that they are sorry for the inconvenience?<br> <br> This is pathetic customer service all round and I want to cancel the upgrade. <br> <br> Please can someone assist me in this regard.
