Scammer pretending to need services and needing funds reversed.

Guy called himself Kelvin Lason said he was hearing impaired and wanted my services. Seems fishy, he is asking me to charge him $3000 extra on something that costs $2000. He says that he wants to pay me extra so I can pay someone else for him. I have to agree that this person is a scammer and I can sense that if I agree to his terms, there will be consequences. He first texts me and then emails by Kelvin_Lason@yahoo.com
