Not specifically as you say, but I have had:

- a UK police force send me a speeding prosecution notice for a car I'd sold 6 months prior to the offence.

- a UK energy company send me to a debt collection agency for unpaid bills they had continued to send to a non-existent address even after telling me they had cleared what was owed and corrected their records of the address.

- a German government official showing up at my door to ask if I was running a specific named business (that I'd never heard of) at the house, which I'd only just taken ownership of from the builder

Someone I used to know in the UK kept getting emails for other people with the same name, including lawyer confidential communications for a namesake who was involved in one of the big banking scandals.

Absolutely. My biggest defences against that include the luck of someone else more famous with my own name.
