Vodacom *****s my money

I accidentally overpaid Vodacom this month. Instead of paying R1600 for my contract, I paid R16000. I then contacted Vodacom multiple times to refund me the balance, being R15000.

its been 12 days, no refund, I've been told that its been sent o admin.

I want my refund, I don't have money for things that have been budgeted for the month. why is Vodacom giving me the run around? I'm about to report them to the ombudsman because now this is feeling like someone is pranking me
