Who called from 7632433504

I was given this number by a supposed HR guy from a company in Phoenix, AZ to call during business hours.  I haven't tried yet.  My training is "taking place on Instant messenger" for 30-40 minutes from 8am EST for the next 2 weeks.  I am now skeptical that this guy is hacking my computer as I am "training".   Thanks for the warning.

The caller wanted to return $199.00 to me for some work that was done approx. 9 months ago.

This is a FREE MJ APP that allow ppl to call free from their cell phone...  This is a default number.  The real MJ jack number start with something like this: *01xxxxxxxxx*.

If it starts with 01 that is an INTERNATIONAL CALL

This number called. Didn't answer. No message so I looked up the number on here and found it was as I though, a scammer calling.
