Who called from 9729967978

Today they call me 4 times from this number. Didn't take a call as didn't recognise the number. I live in New Zealand.

This number called stating I signed up for a make money from home program. NOT!!

Got a burst of 5-10 calls to my mobile number in the past few days.  Caller ID just says "Texas" or "Dallas TX".  I never answered; they left no message.  I don't recognize the number.  Likely spam. Possibly spoofed?

This number is calling me constantly all of the sudden.  I'm in Ohio.  Answered once and they said they're from GTS Pro calling about a money making opportunity.
