Just read what happened to dabstheleo. He need to check the paper work that he signed. It should specify the payment breakdown.
What can you do?
Generally these sort of agents (the one you mentioned) plus a few of the other big boys are very smart.
example: the market has grown by 20% (or whatever) for the last 3 years. Its expected to do the same for the next 2.
Or
Buy through us and we’ll help resell it for you. You’ll make a 100% profit (on your investment of 40,000 only if your lucky, not incl. taxes, comissions, etc.) on the sale!.
They’ll never admit to making a mistake, or they will blame someone or something for the mistake.
If i was him, i’d complain to the INnetwork. Get anyone else that has been messed around and get them to complain as well. The INnetwork are there to prevent unethical practices (also i don’t think they’d want the bad publicity).
