Review SCAM

I CALLED TO FIND OUT ABOUT HOW MUCH IT WILL COST ME TO SEND A CERT.TO ATLANTA.I WAS INITIALLY TOLD GH 40.00 THEN HE SAID IT WAS A MISTAKE BUT RATHER SUPPOSE TO BE 180.00.I WAS TOLD TO SEND MOBILE MONEY SO THAT AN AGENT WILL COME AND PICK UP THE PARCEL.I SENT THE MONEY,RECEIPT CONFIRMED THEN MINUTES LATER I CALLED ONLY TO BE TOLD IT WAS TO BE GH 240.00 AND THAT HE MADE AN ERROR.I THEN REQUESTED THAT I DONT HAVE THE EXTRA SO THE MONEY SHOULD BE RETURNED ONLY TO BE TOLD THAT ITS NOW NOT REFUNDABLE BECAUSE THEY HAVE USED IT TO START PROCESSING WITH AN AGENT.PLEASE LET ALL OF US BE VIGILANT.I MISSED OUT ON CERTAIN BASIC INFORMATION DURING OUR CONVERSATION AND IT HAS COST ME THIS;IE;PARCEL ARRIVING WITHIN 48HRS AND MISSING OUT ON QUOTATIONS.
