Summit Business Management review: Timeshare sales scam

I was contacted from this girl named Jessica WEBB from Summit business management or SSP holdings they claimed they put together a purchase of a timeshare I was looking to sell was sent the paperwork the sales contract looked legit I signed everything move forward just before we were supposed to close they said I needed to get a Mexican tax ID number requested that I transfer $4250 to an account the day before the closing the Mexican they claim that the Mexican government require another $3950 to make the contract happen I refuse to pay and requested an official request to get my money back and they have claimed that they can’t give me my money back and are still requesting that I pay them an additional fee because I failed to meet the contract for sale
