Want to Cancel - no response from SellDirect

I allowed SellDirect to send me a Telkom cellphone offer. I could cancel this offer within 7 days after Telkom 'connected' the service. No Selldirect contact info on any admin received. I checked online - got their info on their website [URL Removed] - no response. No luck on their phone numbers. Sent 2 emails to [Email Removed] - no response. <br> I went to Telkom - manageress at Woodlands (Melanie) said I must send email (directed at Selldirect) to her. I did ... again today. No joy. <br> Selldirect must contact me urgently. URGENTLY. Because of their poor service, they are affecting the way I experience Telkom's products.
