******* Sim Swop and Incorrect debit orders

I received an sms on Friday notifying me that the will be a sim swop on my number. I contacted vodacom to tell them that I did not authorize such. I realized on Friday that there was a sim swop done and my phone is out of order. I went to the bank to block all my account because I was not sure what was happening. This morning I called Elite Mobile about 4 times and I am told the agent who is dealing with this query will call me as he is busy on another line\ he has been busy on that line for 3 hours now. I cant access my funds because of this they tell me my account has been suspended because its overdue. I emailed this people my bank statement over and over again this is not helping. I think this is a police matter maybe we should open a case against this people and as for vodacom they are not helping in anyway
