Makes me want to cancel my account immediately

I accidentally transferred 5 times the normal amount to Vodacom. I called to have it reversed (Standard bank could not do it) on 26 December. They told me it would take up to 14 working days. Today is day 13, so just called to follow up. I was told the call was logged to the wrong department and it will take a further 7 days to receive and by now they have deducted 2 payments from this amount. When I asked if I hadn't called today, would I have not received my money back at all. Their answer was yes. No other answer, no apology. This is just how it is, we are big fish and you as an individual that we take money from, but don't care about. I think if the person on the other end of the line was just the slightest bit apologetic, I might not have written this review and given her a higher score than 0. So basically their attitude is, we provide a service so be grateful. But please don't expect the service to extend to the customer service individuals. They are dealing with too much to be the slightest bit helpful.
