The problem with bank charges is that they are unlawful. They are only allowed under law to recoup their actual loss which, these days to reverse a direct debit or send an automated letter to tell you that you have gone overdrawn ammounts to around £0.35 - £0.50. Anything over the actual loss is unlawful.
There are cases where banks have charged their customers £30.00 for being overdrawn less than £0.05 !!!
I would suggest that EVERYONE who has successfully claimed back bank charges agrees that they should have to pay for any loss the bank has made but until the banks will openly admit how much it actually costs, the customer will never know the true figure.
Why won't the banks admit it ? - because it will reveal to their customers how much they have been ripped off over the years.
