Poor service

I contacted the local old mutual branch in my town to cancell a policy that i did not sign up for, and they tell me that i must bring in bank statement, sars number and id to do this, and then i must wait for 15 working days for them to pay the money back to me that i already paid for somthing i did not want. Im not going to wait for something that is not my fault. Then i contacted Old Mutual head office in Cape Town, was on hold for 20minutes before i just hung up. So i just want to cancell my policy and want my money back asap.
