Utterly pathetic

I am the MD of a Medium company and have many RED contracts. Vodacom has accidently moved my number to another lady's account and she has been paying it for 9 month now. Numourous calls has been made to Vodacom to correct the issue without any success. Now they have just taken me offline and I cant phone anymore. I cant recieve or make any calls and they cant resolve the problem! My number has been blocked because it is not on my account anymore. They cant tell me what to do either!
