Insurance money refund

Last year around October I lost my contract phone which was insured with Vodacom. My claim was declined as the number I was using on the cellphone was not the insured one. I later advised Vodacom to cancel the insurance since there was no phone to be insured. The insurance was cancelled but my money was still been deducted for insurance. I called the insurance department and they assured me that I will get my refund, till today I haven't received my money back. Why should I wait for my money this long while my claim was rejected and why was my money still been deducted as my claim was rejected
