14 working days and I STILL don't have my refund

My third post about shoddy service from Vodacom since I initiated my contract.

I paid R801.72 to my Vodacom account as I had not received any invoices etc and no debit had come off for two months. I was then debited another R801.72.

On the 7th of July I finally got told that I was only supposed to have been charged R399 for the 1st of July as that was my first debit date (I was debited R801.72) & told that Vodacom owed be R401 and it was credited to my Vodacom account.

On the 8th of July I was then told that I would be refunded R802, and it would be in my account in 7-14 working days. Today is the 14th working day. No money and Vodacom is now asking me if I wouldn't prefer 'a credit to my Vodacom account'. I already have a R401 credit in my account according to your team & R802 that needs to be refunded to me.

I want my money and I want it today. I don't know what fantasy world people live in that they feel that R800 is not necessary to return promptly.
