took double money and no feedback

Vodacom Voda pay took my voucher payment 3 April 2025 kept getting messages that it was not paid. Chat to agents several time blame system glitches and they are not very empathetic as they drop chat or calls. Got email to sent proof of payment. Got call 16th april 2025 that matter will be resolved the following day. Saturday 19th april 2025 18:47 money was taken out of my account i went into chat and matter would have been escallated again they call it system glitches bit concerning that Vodacom have so many glitches. Send email no response up until know. Phoned yester and was promised feedback this morning 23 April 2025. No response or even emails response. Had to cancel card and is minus double payment and they have no interest to help. I need my money back that they took without my premision.
