But if you are spending money thats not yours why should the banks let them ?
oftent these cases arent as simple as that. it is not a simple case of someone spending 20 quid too much and then getting charged 30 quid for it. It is more often, when there is already a very tight budget in place, the uncontrollable spiral that this creates. the people that suffer from it are the ones who can least afford it.
so you get charged 30 quid for the bank returning a 20 quid direct debit. you are now 30 quid overdrawn
then, a couple of weeks later you get hit with another charge, for every day you are overdrawn without permission. say 20 quid a day for a maximum of 3 days (rbs charged in this way)
(note that your idea that you are spending the banks money is nonsense. the bank are now actually spending your money for you)
you are now 90 quid overdrawn. your small salary goes in, but you are now 90 quid behind your budget. so you phone up the bank - 'hi, im a bit short can i have a 100 quid overdraft ?'
' sorry, your profile is not the type we want to lend money to. bye'.
(translates as - we can give you an od and charge you 5 quid for it, or we can refuse, and continue to rake in 60 quid per month).
so this continues..month after month...all because of one mistake/oversight/whatever. perhaps you can suggest a solution to this ?
