My account has been locked-down

Prior to 23 June a ********* upgraded one of my Data Accounts and got from Vodacom a new device.<br> When a spike appeared on my monthly billing i went to Vodashop Meyersdal and reported the problem. They then established that ***** had happened on my account and i had to get an avidavid done and it was reported to Vodacom. Vodacom then sent me SMS's to say that they have investigated and confirmed that there has been *****. Since then all my data contracts and cell phone have been locked down as if i am the ********. Vodashop Meyersdal have repeatedly reported the issue as have i on a daily basis to Vodacom call centre. Thembiso a Team Manager of Vodacom last week assured me that he would reverse the Device from my account - nothing has been done and right now i cannot make any calls. This has now been going on for more than 3 weeks - how long does it take to reverse a device incorrectly given by Vodacom to a *********.
