Disgusting service AGAIN from VODACOM!!!!

I cannot believe that I am writing another complaint about VODACOM and I am disappointed to say that since my last review and complaint on the 7th May and (only because I went the official and social route) did someone actually phone me and promise to resolve the issue..... Well needless to say the insurance is sorted out and did not come off my account like it has for the past 5 months despite cancelling it 5 TIMES.... Vodacom acknowledges the issue and the fact that I have canceled it 5 times with reference numbers, dates and times and acknowledges that I am owed a refund but of course as expected NO REFUND on my June account. They are absolutely *********** and useless!!! Can you believe the customer services manager said if it is not resolved to go to social media.... really and then.... I WANT MY REFUND OF MONIES OWED TO ME VODACOM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
