Retrospective caller id

[#1]

I'm trying to find out who called me last week. It was a wrong number and I didn't think anything of it at the time but now I have suspicions about the call and I'd like to know what number it was from.
Is there any way to find this information?

Welcome to the forums!
Unfortunately numbers that have called you aren't something we'd have access to and I'm not sure how/if you'd be able to obtain it.
Unless you'd not received any calls since, and could find out the last number that called you by dialling 1470 1471, but I'm assuming you've received other phone calls since the one in question.
EDIT: Must have been a typo

1471 may be a better bet, rather than 1470
