Did they cold call you? Can you tell us which shares they were selling?
As a general rule if they cold called you and you bought shares then you've been scammed. The website follows the usual pattern and a lot of the content is just copied/pasted from other websites.
Their office address is a Regus serviced office, in fact its most likely a virtual office or maildrop that they have rented from them. There have been dozens of scams operating from Regus offices around the world.

I think its safe to assume you've been scammed. Anyone else who calls you offering anything to do with shares or investment is going to try to take more money off you. Dont believe anything a cold caller tells you and dont part with any more money no matter what excuse you're given.
