I think I may have posted this story once before, but it really was a brain-hurty moment...
A couple of years ago, DH and I suddenly discovered just before Christmas that our accounts with BigUKBank had been frozen and when DH tried to withdraw money, the ATM ate his card. So we went in to the bank to try to sort things out, and ended up speaking to a manager.
It transpired that the postal service had temporarily decided that our address didn't exist, and had started to return all post to the senders. (We don't get much post anyway, so hadn't noticed this.) BigUKBank had sent us statements by post, and they had been returned, so they had put a stop on our accounts.
We asked the manager why BigUKBank hadn't tried to contact either of us before stopping the accounts. 'But we did - we always do,' he replied. 'We sent you two letters by post to alert you to the problem.'
But why did they send us letters by post to an address from which post was being returned?
'Oh, we always send letters! Some people don't like to receive notifications by phone.'
We did try to explain why this made no sense, but I really don't think he ever got it.
