When I got the call my phone said it was suspected spam, so I hung up the call. It IMMEDIATELY started calling again, too fast for it to be a person typing in my number, so I knew the call was automated. I hung up a further 4 times and each time it immediately called me again. They gave up after 5 back to back calls. Never answered the phone so no idea who it was.

Caller: I don't know

Couldn't find any reference to this number so assume its a scam or telesales caller
