VODACOM FAILING TO BLOCK MY ****** NUMBER

Since 16th January I have been calling Vodacom to block my number so that i can get a certain number that shows that my phone has been blocked because my phone was ****** and i need to claim, Vodacom failed to help me to block. I spoke to many consultants who kept on transferring me from one department to another and that is very frustrating. Insurance companies only gives you certain period to claim for a ****** phone. Last time I called Vodacom I was told that the people who promised to block my number did not do it. To my surprised I'm still not assisted. Now i have no mobile and i really need it because i have a pregnant daughter and i will need to have a phone incase of emergencies. Also what if the people that stole my phone starts to make ******* things using my number or even borrow airtime or any advance? Will vodacom account for that?
