Premium refund-EXCESSIVE DELAY

Cancelled, with immediate effect, my vehicle insurance policy, on February 24th,2015 (submitted notification by email). Received a call on March 5th, from Jackie de Bruyn, confirming cancellation. .I requested refund of the premium deducted for March, which had been deducted on February 25th.Jackie assured me I would receive a refund. A confirmatory email was sent the same day, from King Price, stating the policy would cease to be effective from March 6th. NO REFUND HAS BEEN FORTHCOMING. I sent a follow up mail request on 10th March-NO RESPONSE, NO REFUND. A phone call to their client care centre followed on Monday 16th,and the gentleman I spoke to, gave me a story about the company experiencing problems with refunds since their migration to a new computer platform, but assured me he would speak to his supervisor, and that, while he could not give me a date, technicians were working on the problems, and these should be resolved in a day or two. It is now FOUR DAYS LATER, AND STILL NO REFUND! The sad thing is, the amount is only a few hundred-what if it were thousands? Tuesday next week is a month since I cancelled-I DO NOT BELIEVE \COMPUTER PROBLEMS"CAN TAKE SO LONG TO SORT OUT"""
