********** insurance covers ???

I am so very ****ed at Old Mutual right now. They keep signing me up for these ********** insurance covers that I know nothing about. Late last year I was calling them back and forth trying to solve one which they put names of people I don’t even know as my beneficiaries. I have no idea how they got my Persal number. Even today I’m getting an email that I’ve joined a cover for Thabo Shezi. A cover that costs close to R500. My God how do I erase my information from these people’s system. This is so ********* and it’s exhausting. ??????
