Terrible Service - refund issue

Topped up twice in October - money went off my accounts, but the data wasn't loaded - phoned in - so unhelpful. The next day - woke up with the data loaded - only to be billed at the end of October for money that has already come off my account!!! I have been on call since monday trying to get my money back - sent through proof of payments. NO ONE BOTHERS TO CONTACT US BACK REGARDING FEEDBACK!!! Every time I call in - I hear the same story - theyve sent a teams message to billing, theyve sent an email to billing - customer services cant help me. If customer services cant help me with my money issue/refund then why is there no one at the billing department i can speak to???? Ive spoken to Keith, Thandlowthu, Vuma and some manager/teamleader who no longer exists apparently - Phiwa... I have wasted my time and money by calling every day - and not one person from Supersonic has contacted me to give me feedback as they have said that they would do - this included a Dorothy from billing, who apparently credited my account with the proof of payments received - but couldnt bother making contact to tell me about my refund,,, This service is disgusting to say the least - and the fact that 80% of these complaints are about the same issue is extremely concerning - please do not respond with some generic response that will just **** me off even further - please get me answers as to when my money will be refunded. I expect feedback before close of business today.
