Vodacom Masterpass theft

On the 11/1/2021 I did an airtime top-up of R500 on the Vodacom app using MasterPass. This charge came off my credit card, but I have still not been credited with the airtime. I phone and after having to deal with the ridiculous bot, finally spoke to Shadrack Tsotetsi. He asked that I send all the relevant info to his email address, but 10 days later nothing has appeared and he stopped replying to my mails. I phoned again today and was in contact with Rodiszani (she refused to give me her surname, said it was not Vodacom policy??!!!). After a few minuted she started shouting at me telling me "how could she fix this?" - she was incredibly rude and obstructive... absolutely the worst customer service ever.
