Last week I ventured back into the Dark Ages when I decided to close my Internet Savings Account with the Post Office because they were unable to give me a decent interest rate. (They offer a good rate to new customers but cannot transfer existing ones onto it for reasons that completely baffled me.)
So I phoned them up, went through all the security verification to prove who I was before being told that I needed to write to them in order to close the account, as they needed to compare my signature with the one they had on record. I protested that I was only asking them to transfer the funds into my nominated bank account (that they already had the details of), but soon discovered that I was wrestling with fog.
I gave up and sent them a letter. Yesterday I received a reply which asked me to send another copy of my signature because they did not after all, have the original one (that I used to open the account) on file.
I have duly complied with their request, but my brain hurts from puzzling over what exactly they intend to compare with what.
