Call centre noise behind the foreign voice, said he was from the debt agency, told him he had wrong number and hung up. Only called once and hopefully this is not the start of a stream of calls but will block and hope for the best, they will have dozens of numbers to call from
Reported caller:
Didn't give me a specific name, only that it was a debt agency

They say they are citizens advice and debt collectors have contacted them about me. Definitely a scam.
