Bad service

I made payment to Vodacom on 22 March 2025, I noticed that I transferred R1600. to the wrong account when I made EFT. I called them and send proof of payment and bank statement as requested. Was told that they are unable to trace funds. Been communicating with them with email . Now they are quite so far for the whole 2 months they even blocked me for calling them to anquire how horrible they are. Money was donated to charity or what, I don’t understand how can they do that for their customers. As they know they have multiple accounts why can’t they check them all instead was told unable to trace. Iam not happy at all.
