No response from Customer Care Email Facility

I have a R 30 life policy that is being deducted off my bank account. I am presuming it is one of the old life policies but I have no recollection of signing up for it. I have tried to call the Old Mutual Customer Care offices on 4 occasions and get pushed from pillar to post. To date, no one has been able to help me. I eventually emailed the address they gave me and although I have received 3 reference numbers, I have still had no response from them. It is incredibly frustrating dealing with such a big company and receiving such poor service.
