waiting 7 months for refund

I was doubly insured by IWYZE and M&F for my house. I cancelled my policy with IWYZE in January 2015 (active since August 2014) via e-mail, and was promised a refund as I was doubly insured. In May 2015, while still deducting my premium every month, I got hold of Mr. Skhumbuzo Mungwe. After I e-mailed all correspondence that I had with IWYZE up to date, he promised me that he would cancel my policy and refund monies owed to me. Thinking that all was sorted, I couldn`t believe my eyes when I saw an IWYZE debit order going off my account on 1 June 2015. I immediately contacted Skhumbuzo again, and on 3 June 2015 got a confirmation letter stating that my policy has been cancelled, and an e-mail from Skhumbuzo stating that he would revert back to me within 24hours on my refund. After several e-mails to Skhumbuzo after that day, while I cc in [Email Removed] no answer or refund ever made its way to me. Now all I am left with is to report it to this site. I have never encountered such bad service, and am thinking of cancelling my M&F policy, R1799.65 deducted every month.
