Sim card activation taking more than 4 days

wifi router was delivered 04.03.2015 since then no sim card activation. I have phoned numerous times and everytime i get told the line will be activated in a hour. We are on the 8 th and still no active sim card. I purchased this router over vodacom telesales and can not understand why is this taking so long. I have been with vodacom as long as I remember ans if i go to the vida shops i never have this problem. If it can not be activated soon i will cancel the contract and go to another network.
