Why do companies like KIVC still get away with what they do after having scammed so many people with their lies and promises for so many years!!
What would you have them do differently? They (by Mexican law) already give buyers 5 days to review the written contract and cancel the deal for ANY reason. That people choose not to read or act on it within that time frame is really not their business. There is a requirement that the buyer be told about the rescission period during the sales presentation. We suspect that that requirement could be as simple as them saying, 'You've read and understand this translation of the contract, No? Initial here.'
There is also the custom of pressing guests to do the presentation in the first few days of their visit, then loading them up with tours or zip-lines, or who knows what, so that buyers just don't have time to read a dry, ol' contract and act on the fine print that is buried within it. Yes, it's deceitful, but the business model works. After all, if buyers were totally informed that a timeshare will lost 95+% of it's value the instant you buy it, and that buyers are stuck with annual payments forever, and that the only value of the TS is in it's use, NOBODY WOULD BUY!
We have posted 'Things to know before attending a Mexican timeshare presentation' and 'How to Rescind' and many other guides on the subject- up in the red-tinted stickies at the top of this forum, but if people don't even take the few seconds to do a Google search at some point during those 5 days after making a large impulse purchase, we can't help them.
To answer your question, they do it because it works. And it isn't just Mexican ones like KIVC, American ones like Westgate are just as bad.
