Who called from 7167941350

The female claimed that she was from a job recruitment office even though I never was on any site like that recently (meaning about 3 years).

Same here! I've never ever been on a site like that.

Same.

I just received three calls within one minute from this number. They haven't left a voicemail either. It must not be of any importance.

Same here, Three calls, less than a minute apart and no voicemail.
