I WANT MY REFUND AS PROMISED!

I am back again. Despite what Vodacom did to me in February regarding paying off my phone and they deducted again while I was never informed about that. They doubled charged me for insurance and the agreement was that I will receive my refund. It’s been more than a month now without receiving my insurance refund. At this point I hate this brand with all my heart. I’m a loyal customer but I can’t believe that I am treated like this. During the contract period i’ve never missed payment even once but I am treated like I don’t matter as client.
