I have just incurred bank charges for going overdrawn on my current account. And because that bank charge again took me overdrawn, I get another bank charge. Okay, it's only £30, but they don't know who they're dealing with. So for a start I switched to First Direct, and that got me money just for switching. Next, apparently if you take the bank to the small claims court to ask for the money back (as in my opinion, £30 charge for being overdrawn by £16 for two days is excessive), it only costs £25 and you don't have to pay the bank's court costs if you lose. So, for me, the £25 is worth it to find out not only how the small claims court works but also whether Nationwide thinks it's worth paying to go to court to keep my £30.
