Outstanding Debit Card Authorisation

I have swiped my card at a garage and for some reason the network went off so they have said that i must swipe again, when i got home as my phone was flat i saw that the money went of twice and went back to the garage and given them the slip and everything they have said it will be reversed.<br> <br> Yesterday i went to fnb as the garage is not doing anything, was sitting at the branch for a while and then the guy told me i must wait 5-7 working days, I want to know why must i wait for my own money that is in my account under Outstanding debit card authorisation and it even shows on my statement that the money went off.<br> <br> This is really a ******* as you still need to investigate first after i have provided all information and it shows on my statement. if this is the case how you treat your customers now ill have to change banks
