Who called from 7402996400

How often?

I have gotten calls several times in the last 2 weeks and all they say is hello and couple of times and when I say you got the wrong number he hangs up and then calls again.

Calls and says hello hello I must have a bad connection.  Calls back, states my name and then hangs up.

Called and said they were Prestige Resort Exchange.... gave number to call them back as 877-258-4793...  called this number and it is not in service..... called back the 470-299-6400 number from caller id and it is not in service.

Got a call. Blocked it from now on.
