I took out a life policy for my mum last year April

I took out a life policy for my mum last year April. The application was approved and all went well until they send me the policy documents where my mums name is spelled incorrect. I have emailed and spoke to Charle the consultant on numerous times to rectify the matter as I don't want any surprises when it's time to claim one day. Charle Rei Lutonadio assured me on numerous times that it will be rectify but I'm not getting any joy from him. He has my mums information since last year and yet his not updating anything. Yesterday I send another email to him and he does not respond at all. I've seen on TV and social media that old mutual does not update the clients policies in order for them not to make payment when it is time to claim. Really dissatisfied and dissapionted with old mutual and the staff that works there.
