Who called from 4842426270

I got a call from this number at 8am pst, I was asleep so no messege left. Called back, I actually got a "this number is not in service." Usually call centers from other countries try to bounce calls off of US phone numbers, so this is definitely a scam marketer calling.

This number called at 2;30 am.  Then called our other phone line at @ 3:30 am.  No one on the line both times.

Just received call from I 484 242 6270 showed on caller ID as receivable mana.  No message left

Got a call from that number here in ND, did not answer it, no message left.

Received a call at work from 484-242-6270 twice, 3 minutes apart. No message left. Caller ID stated Receivable Management. No clue who they are.
