If you have been communicating with someone and they went to Nigeria or Ghana and this person is now telling you they need help with funds for their business, travel including airfare or "BTA" -which is a non-existing thing, medical expenses or even the hotel/accomodation bills yes you are in a scam.
Also a legitimate business doesn't use hotmail, gmail or any of the other free internet email services. They would have an email address associated to their business. Phone numbers given to you are numbers of the accomplices involved in the scam.
