No service No Help

I called Telkom Mobile, I have called Sell Direct no answer with Sell Direct on any number. I took a contract via them for Telkom Mobile and on Friday 03/07/2015 they phoned to activate the sim card. To date the sim is not activated. Telkom Mobile cannot assist me in resolving the issue even though I am their client also. I chatted to Busisiwe and Chanell Belo who politely ignored my questions and simply left the chat open with no response. I am being billed for a contract which I cannot use as the sim is not activated. This company acts on your behald yet there is no communication and assistance from either side. When I spoke to your Call Centre they said keep trying until you get hold of them!!! Thats not a good enough answer and someone out there must have a contact person at Sell Direct. This experience has been so bad and utterly disgusted in the way clients are treated. After sales person on both ends have no care just complete disregard.
