Helios Commodities

I've been dealing with Helios Commodities for over a year now, trying to sell my timeshare. The timeshare is in Mexico. They told me I needed to get a tax id and temporary Mexican citizenship in order to sell. They have paperwork for everything. They appear legit but I seem to have a fee of some kind to pay for these things. They attempted to wire transfer my funds but they misentered my account number. The bank sending the wire wouldn't claim responsibility and they had to use another bank, which wanted a bond to ensure there was no money laundering. Has anyone heard of or done business with Helios Commodities? What was your experience? Thanks,

Everything about this says "Scam", especially the part about wiring money to Mexico. If you have already wired them money, consider it long gone and an expensive lesson.
