Okay, phoned them up and im slightly less irate...
of the £200, £75 was 'in error', but £125 still remains.
They charge you £25 a day, on days where you withdraw more than £20. So because i paid for petrol on 3 separate days, and 2 bills went out on another 2 separate days, they have charged me 5 times.
I asked if, god forbid, i knew i was going to be overdrawn again that if i go and withdraw £500 cash on one day, i'd only get charged £25 once - and she said yeh - you can get round it that way!
Unbelievable..!
