Who called from 3479212563

This is a scammer! They also send texts saying "You have won $250,000 in the T Mobile Sweepstakes"
AT&T just announced they are acquiring T Mobile. Don't fall for these scams!
Message also says name is GARY NASH. Probably FAKE!!! and to call between MON-SAT 8-5.

I have been getting calls from a Gary Nash, think he is scamming me. The number he is using is 347-478-8239 is this same one?
