Banking scam!

I just realised that the banks are running a crafty scam to trick people into spending their money and getting into debt! I went to the ATM to take out £20 in the week last week. After I had entered the details, a message flashes up on the screen — “you have not been charged for this transaction”.

“Oh well, must be something up with the machine, never mind”, I think. But then, to my surprise, out comes the double–sawski notwithstanding. “Superb!”, I think, “could be time to fill my boots”, so I put in for withdrawing £500. Again, “you have not been charged for this transaction” and out pops the monkey.

However, with the money long gone on exotic fruit and fishing equipment, imagine my surprise and disappointment when my bank statement arrives today showing that contrary to the message on the ATM, my account has in fact been charged for both those transactions — £520 down — which, because it was end of month, puts me well into the red. What a scam!

Have I got any legal action against the bank for this?
