Pay back my money

<p>I had a vehicle finance with standard bank which I have settled on the 12 April. On the 20th the still debited my account. I phoned them requesting my natis document and my refund. The natis document was only delivered on the 10 May. I have been taken from post to pillar for my refund. I spend every morning on the phone with them, but still they won't pay back my money. It's almost a month now of no success and I have ran out of spending money now I had to use their credit card which they will charge me interest on while they don't want to pay me back.</p> <p>When I phone they always tell me that they will escalate my issue and phone me back, but they never did. This is the reference number ********** 917. I find this to be very unfair for me as a customer.</p> <p>Please assist.</p>
