Quick Sale - Zero Follow Through

I was telephoned by a sales rep trying to renew my Telkom Mobile modem package. I told them I was cancelling the modem but would be renewing my cell phone contract if they wanted to do that over the phone. I spent 20 minutes on the telephone supposedly renewing my cell contract and was told I would receive delivery of my new phone and SIM in 4 to 8 days. Two weeks later I was still waiting. I then received 2 phone calls from other reps at SellDirect trying to renew my cell contract - something I thought I had already done. After much fuss and 2 emails, I received my new cell phone a week later... but guess what NO SIM CARD. Having eventually reached someone at the call centre, I was told a new SIM would be delivered the next day. Three days later I am still waiting. I have tried calling the call centre more than 10 times... no one ever answers the phone. Telkom Mobile are unable to assist as they can't access the SellDirect system. This service is appalling.
