Who called from 4168258388

Sent me a letter enclosing a check for $4,850.00 and told me not to cash it until I call this number.  The letter is from a John Carfield at RBC Financial, International Finance Department, P.O. Box 4545 Windsor, Ontario, Canada.  The check is from Midstates, Inc., 1774 W. Wesley Avenue, Englewood,CO 80110 and the bank issuing check is Wells Fargo Bank, 2350 E. Arapahoe Road, Littleton, Co 80122.

Is this a hoax?

Take it to your bank and see if its a real cheque. I'm willing to bet it's a fake.
