Delay start of contract

I opened a new contract (Red Advance) on the 30th April, according to my contract my phone will be loaded and ready with all my data and free minutes on the 1st May. 04th May the branch contact me to come and collect a new sim card because I have the wrong sim, they told me that the sim will be ready in 2 - 3 yours. On the 4th may 18:00 I inserted the vodacom sim because my previous sim's data did not word anymore. I contact vodacom for assistance because the phone still did not have my data of minutes. <br> After a few minutes Carnival Mall contacted me regarding the sim, the lady told me I need to come in the branch today @ 9:00 to collect another sim. The lady who contacted me the previous night was not there and will only be in at 11:00. I spoke to a bold headed guy and explained to him the story. He gave me the new sim and told me to phone 100. I phoned 100 they told me my number will be prepaid (just like the previous sim card). I asked him way my sim are prepaid because it should be a contract number. According to him it will take 24hours. I told him it should have been active 1 May (they are braking contract already) he told me the 1st was a holiday and walked away.<br>
