Timeshare buyout from Kallpa

Anyone hear of a timeshare buyout from Kallpa, a tour operator in Argentina? https://kallpatour.com/experiences/

This would be for a t/s owned in Mexico. Hesitant and skeptical, but also curious.

Thank you!

Usually the pitch goes like this: Someone (anyone) offers you a large amount of money for a Mexican timeshare. Might even be more than you paid for it. You get excited, get a contract, and it seems so good. Then, they tell you that you need to register with the Mexican government, or pay a capital gains tax, or or pay a foreign purchaser tax. Tax, tax, fee, fee. If you send money, they will find another charge to impose. Until you realize that the money isn't coming back and you realize that you can't get in touch with the foreign buyers.

Common scam. Best to avoid all contact. No one want your timeshare.

How did you find out about this company? Was it an unexpected telemarketing call? How much are they allegedly offering to pay for it? A lot more than what it is worth? Did you even have it advertised for sale?
