I had some paperwork refused on my business account with Lloyds because it "didn't match the signature on file" — I went in to the bank with photo ID and got my stuff sorted and happened to ask "Can I see the signature that you have on file for me?" (because generally it doesn't change that much for me time-to-time) — it was a completely different person! Wasn't even my name. The cashier agreed with me that it _clearly_ wasn't my signature & "didn't know how it happened". I was in a big rush that day & no longer have the account, but I really regret not escalating it though.
