thanks for your comments. We are unlikely to ever do this again after this experience. I have heard from Global who are taking advice. Basically it's a mystery to me how we came to get Mobilestream Oil Inc stock after such a scammy sale, but we did and have the certificates to prove it!
You may have noticed from the figures that my folks ended up paying over $81,000 for a $55,000 purchase. What happened to the other $26,000?
