Not happy with Vodacom service

On the 21/12/2020, I bought R130 airtime using vodacom app, 2 weeks passed without getting that airtime but it was deducted from my account, after that two weeks I called vodacom multiple times querying it and they've been telling me a lot of stories, on my second last communication with them I demanded my money back that was around the 10/01/2021, they requested proof of payment and I sent it, they advised that within 7 days I will get my money back, I’m still waiting even today is the 24/01/2020, so this is how they eat people money, they are not practising TCF... I wonder how many people experienced the same but don't know where to get help...
