Refund

i paid my account twice on the 1st March 2016 and soon as I realised I went Standard Bank to reverse the other payment as it was a mistake and I do have other obligations and commitments. I was told it would take 2 working days, I went back on the 3rd and it was still not done and was told that they'd been working on it and would send an sms that day once the process was done. I went back again on the 5th and they knew nothing about it and the lady was talking to a Tshepiso who was doing it and said refund would be done in two days. Today it's the 9th and am still waiting. NOTE: I blocked Standard bank about 2 years ago from debiting my account because I had called numerous times to change my debit order date which was an epic fail. Standard bank is run by *********** selfish bunch of people with no regards/ respect for clients but until I get my refund I will NOT be paying them a dime. They will wait until am ready since my other commitments are having to wait.
