AVBOB disappointed me

I have a problem that someone used my details to join a policy for me without my knowledge or consent. I am asking myself how did AVBOB go ahead and process a policy without my consent and my signature. Where did they get my documents?? They have done me so wrong and I am so disappointed. I have never spoken to anyone from AVBOB and never agreed to anything. the policy was processed from March. I made calls and told them that I want my money back and they are telling me a lot of stories. They say I should fill a complaint form and wait for 5-6 weeks for investigations. I cannot wait for such a long time as I need my money. I spoke to guy called Kwanele from AVBOB and he told me that the policy was finalised in March. So need a refund of all the months that they have been deducting.
