Vodacom's *********** Accounts Department

I paid my bill on the 27th of January via EFT which I've done for over 10 years even though I had a debit order set up BUT never had my account been debited. Well today things changed. Vodacom decides my credit of R920 wasn't good enough for my bill which was R918.20 so they decided to debit me. I phoned the solutions department only to be told by Tebogo that it takes 7 days to refund me. I WANT MY DAMN MONEY BACK RIGHT NOW. YOURLL WERE TOO QUICK TO TAKE IT BUT CAN'T PAY IT BACK. PATHETIC! DISGUSTING SERVICE!!
