They MUST process the rescission. They are under no obligation to give you any progress report, or do ANYTHING except process the rescission and refund your money already paid. It's possible that you'll get calls from the sales dept to try to dissuade you, offering all kinds of additional bonuses and perks. Best to not answer any calls from numbers you don't recognize. It could take up to 45 days for a credit to appear in your credit card or bank account (wherever they return your down payment.
You should return any promotional materials to them- do it by cheapest means.
And you're done.
If the concept of timeshare still appeals, take your time. Study here at TUG university. Find some nice resort that works for you. Most importantly, if you choose to buy, buy resale. But really, today, you can rent for (in many cases) less than the cost of MF, and with zero buy-in cost. You can find these rentals in the TUG marketplace (red stripe above here) or in Last minute Rental forum- where they are limited to $100 per night, or on eBay od Redweek.
We're glad you made the smart decision to rescind and do some studying. You can quietly and thankfully count the money TUG saved you.
You're welcome!
