Prepaid number

I went to a telkom store 2 weeks ago to transfer my contract package to my prepaid number and they told me it was going to take 72 hours. More than 72 hours later I found out that they changed it to the wrong number, they changed it to a data only Sim card. I called after I found out, I was told to go to a telkom store to change it to the right Sim card , which I did last week Tuesday and again I was told it would take 72 hours. It has been more than that and I have been calling and calling but I have been receiving different answers. I called on Saturday I was told the people responsible for that don't work on weekends, I should get back to them on Monday. I called back again on Monday and I was transferred to the contract department and I was on the line for 10 minutes without any help until I hung up. I called in today and I was told that I need to go a telkom store and change it there. Even if I go to a telkom store they will log a case and give me a reference number and I will have to call the call center to find out the progress. I have been sent from pillar to post for two weeks by people who work at Telkom telling me different things, and I don't know what to do, but all I know is I want my number back. I have used that number for years and I have used it to open accounts, look for jobs, at work I use it so when they need me they will get hold of me, I'm already getting in trouble at work because when I get called they can't get hold of me, I'm sick and tired of calling for the same thing over and over again. At this point I don't know what to do because I'm getting different answers, but all I know is I want my number back, I'm not going to change my whole life because someone made a mistake and now I have to pay for it.
