Nedbank *****s your money

On the 13th July 2015, I filled up my vehicle at Caltex Monument - My account was debitted for R650<br> On the 14th July 2015 - Nedbank debitted my account again.<br> Apparently there was an issue and it would have been resolved, <br> Contacted the call centre on the 20/07/2015 - and was told that matter would be resolved within 2 days<br> Honorary fees where deducted due to funds being too low - which it wouldn't have, if Nedbank had not debitted me twice.<br> It is now 23 of July 2015 - 1 1/2 weeks later - and still nothing<br> Contacted the call centre, and after being passed from pillar to post - now being told that they have not attended to it as yet.<br> Thank you Nedbank for *****ing my money, and collecting interest against this - while I struggle
