WRONG PHONE

I placed my order on the 23 April and my order was pre-aproved. R249 was debited from my acc on the 30 April. Received an sms on the 2 May stating that my order will be processed shortly and have not had any communication Telkom after that.

So this morning (15/5/2018) 15days after i payed for a product that i don't have in my hands i get a call from a courier guy that's delivering my mobile phone. He hands me a sealed package which i signed for without opening. When i opened the package i found a gold phone instead of black and the phone does not support dual sim which i requested and insisted on the color black but got gold. Tried calling your call centers and spent almost an hour waiting for an available agent. So please help me cancel this contract as i cannot deal with i service provider that works like this.
