Poor service,*********** manager, charged twice

This was a first for me, I placed my order, paid via debit card, right after I entered my pin the machine died.<br> <br> The manager(black lady) kept arguing with me that the transaction did not go through and I kept telling her that it did ,she insisted that I swipe my card again, that I I did.<br> <br> Got my food(double crunch burger and large coleslaw), I got home and the bun was so old that it fell apart, the coleslaw was so dry that not even my neighbour's rabbit wanted to eat it.<br> <br> Next morning I received my bank account notifications and sure as hell I paid twice like I told the manager that the transaction did go through.<br> <br> Now I need to take time off work just to go to the bank and get printed statements to show that the transaction went through twice to get a refund.<br> <br> This is not acceptable for me, can we resolve this without me going to the bank for statements?
