I have a phone number from Africa at which should be RMJ Shipping company. The phone number is 233278777857.
...and I almost forgot, there is no record of the number on Truecaller
+233 is the country code for Ghana. Have you tried dialing the number to find out? Text messages are being delivered to the number but I can't find any company website.
you can contact the embassy
My search did not reveal any previously posted reports of fraudulent behavior. I was not able to dial out to this number. You need to get in contact with RMJ see if they can identify the number as their own or schedule a phone call with a verifiable representative.
