Debiting of account after cancellation

After cancelling my insurance policy at Oaksure in December, my account was debited in January. I called the company to ask why and to get a refund and spoke to Joseph Ndlovu who told me to submit bank statements to prove that the debit order went off. I submitted all that they required and yet its end of April and I still havent received my money back. When I call them, they tell me I will get paid or refer me to another department and eventually the phone is hanged up. It been 4 months and I have not had any calls instead I am the one that must run after them. This is absolute nonsense and I will never ever refer anyone to join Oaksure. Clearly this is how they do their business.
