Who called from 5159645535

called 2 times, no message left, but when call back, phone does not ring

Wanted to do a survey on our business.  Wanted the business name, annual sales, how many employees, what employees income was, did we have benefits.  They didn't like the words NO THANKS!

This company is Praxair in the U.S.  They are legitimate so not sure why they wouldn't identify themselves.  We deal with them all the time and never have had problem.  A cliche somewhere.

Called and asked for our old business name. I told them our New name. They would not say why they called. They just hung up.
