To protect yourself and your business from fraudsters, please ask for company documents, vehicle documents, GIT documents where applicable and some trade references.
Do not make payments to transporters or brokers upfront without doing some reference checks, verifying company details, verifying ownership of vehicles or until the load is complete. Get as much documentation as possible.
Beware of posts like the attached asking for upfront payments. They are also operating from a gmail address so you cant establish if this is a genuine offer / business etc. Unless you know the person and have all legal and correct documentation, then it would be safe to do business with them.
