No feedback/communication regarding new contract

I recently placed a call-back with Telkom Mobile on the website regarding one of their mobile deals they currently have running. I received a call from a Kuben Govender regarding my query and took out a new contract with Telkom Mobile. I placed an order for the new iPhone 6. The next day my account was debited for the full amount of the monthly subscription. I then received an email advising me that the colour I ordered was not available so I decided to take the iPhone 6 Plus. It is now a week since my last conversation with the sales consultant and I am unable to get hold of him via email or via the call centre number 081180 which just never works. I am extremely disappointed in the bad service that I have received and am now wondering whether I have been ****med.
