Contract Don't Exist

I went to Telkom Mobile in Rosebank and took out a contract on Thursday, I was assured by the sales agent that the porting would take place through the night and by the morning I would be with Telkom. By 7am I got worried and called the store several times and there was no answer. I emailed the sales consultant who intern got back to me saying that I left the store with a phone but my contract didn't exist, so I shouldn't even think about the porting right now. At 16:05 I went to the store and asked to speak to the store manager, I was informed that she had left for the day so I asked her to be contacted. When I spoke to Heather she was so rude to me and actually hung up, I then asked to speak to someone else & was intouch with the area controller, who I explained my problem to, after we spoke and I was expecting feedback which I hadn't gotten, when I called the area controller again his phone was off and has still not gotten back to me today. I wish to cancel this contract and never deal with telkom again.
