Don't know this number. Not expecting any calls so didn't pick up.

This number called me, the phone only rang for 3 rings then hung up. I assume that I was on a list of numbers simultaneously called and that as I didn't pick up first the call to me was terminated. Probably a marketing call or a spam call or a scam call. If it was something else they will probably call back.

Don't know the number did not answer had it been important a message would have been left on my voicemail.. I'm assuming it's a spam call!
