Old Mutual has no ethics

I have endless trouble for months now getting Old Mutual to pay back a premium on a policy which I have cancelled before the first installment were to go off. I took out a policy with them in 2020, but with Covid, things changed drastically with my financial state and I had to cancelled my policy with them; which were done way in advance of the first premium going off. Although the reversed the first debt, the following month they debited my account again. I have submitted endless documents and signed several letters with them where they keep on promising that they will return my money after they received the documents. I have done my part on many occasions, even more than what I should have, but still they making excuses to why they not paying the money back. I took out the policy with a man called Chris Naicker who is working with a lady named Sarah who is an Old Mutual Agent from Chatsworth in Durban. Guys, be very careful when dealing with these companies like these, they only want to take your money, but when it comes to reimbursing people who can't afford their products, you get treated like a dog
