Got same call from same number, think it is a scam

I got three calls from this number and when I answered, it was a man trying to get my personal details because I had apparently spoken with him two week prior about getting more money back from my tax. I assured him that I hadn't and then he confirmed my full name and address. When I told him I was a student and didn't get taxed he promptly hung up :// I think it's a scam of some sort.

Not sure who’s number

This number has called me multiple times, doesn’t leave a message and if I call back there’s no connection. Number has now been blocked.

Keep ringing me.annoying

Called this number back. Went to voice msg apparently this number is being used by telemarking scammers without consent of owner. Have followed instructions by owner to block number.

I called back number 0437 368 810 rang once then gets disconnected automatically.
