I recently had my overdraft withdrawn and had to pay it off all in one go.
The bank was being really 'difficult' about discussing it with me until I placed a wad of cash on the desk and asked if they wanted it or not.
Then they got very charming and were a little concerned that I might want to close my account. I considerd it but thought I'd leave it open as I had bills to pay.
I then had a huge lump of money removed from my account for 'unauthorised overdraft fees even though I had paid it off.
I argued it and got some back but they said the charge still applies up to two months after the overdraft was cleared, however, had I closed my account immediately when I cleared the overdraft the charges wouldn't have been levied! Now had I known that....
I closed my all accounts immediately, current, savings, student and business, and took a wad of cash and all my business away with me. Their loss overall as they made a lot of money out of providing me with banking services. Still, its only a drop in the ocean that the bank wouldn't even consider as an issue. Bet they would if everyone did it though.
