Woolworths Feedback

On the 30/03/2016 i made a payment on my account using my debit card and there was an error two payments of R600 were made, the cashier promised to reverse the transaction and refund my account with the extra R600- Up to date no feedback was given had to go to the Bank to check if something happened ... Zero...!! Then i went to the store today 12/04/2016and was told they were meaning to phone me before i walked in.. to my suprise my money can not be refunded because the cashier who assisted me is not at work i have to wait for her to come back then they can refund me, I should waste my petrol money again and come back \maybe\" she will be in on sat or sunday. This was after i was asked to wait for her for 3 hours-my time - my petrol - my energy ...I never had any problems with woolworths but this makes me wonder , is the service dropping or is because i was in soshanguve ?
