post bank never works

<p>I have been using post banking for quite a while and recently my money gets taken off when there is an error while swiping my card. It has happened twice before now and this is the third time. I was at good *****s marketing Silverton today and at 8:50am I tried to swipe my card and it gave the store an error and it was still taken off my account twice. R41 went f my account twice and I still had to pay cash because they kept getting an error meanwhile post bank was taking money.</p>
