unknown fees

On the 15th of June i went to a restaurant and paid for my food with my nedbank cheque card, the money was debited and then debited again 2 days later. The second debit was then reversed but i was charged an HON Fee of R90. So i phoned nedbank to find out what had happened and the lady i spoke to was very kind and explained to me that when i paid the restaurant initially the bank systems were offline and so i was double debited. they then reversed the second debit and were not supposed to charge the reversal fee of R90. She then said that R90 would be reversed as well but she cannot tell me when. So now, 5 days later im still R90 short, its month end and i dont know when i will receive that money. R90 may not seem like much money but that could be 2/3 days worth of lunch... <br> Iv enquired with FNB about an account and have received such impeccable service that i think its time to change as this is just one of the issues iv had with nedbank over the years..
