It's was August 2008 my family went to Cancun Mexico. We used our USA timeshare to exchange a week there. We were offered a timeshare presentation from the local travel agency in the hotel and we accepted because of discount tour tickets for our time. We went to Groupo Mayan where was 45 minutes away from our hotel and it was located in mid of highway. We were there since 9:30am until 6pm. The guy who gave us the presentation spoke very good English and said he was a lawyer and completed his high education in USA. he also told us he was from a rich family and he makes over $10, 000 per month from Group Mayan. Wow what a salary for a Mexican!!! We were convinced by him that our current timeshare was nothing to compare to Groupo Mayan. He also promised us to sell our timeshare although I doubt it. But we were so tired and finally purchased their 4-week vacation for over $25, 000, with the mind that our own timeshares (2 of them in USA) would be sold by them within 30 to 60 days. We paid the entire amount by using th credit card. After we went back to the hotel, I read the entire package. More I read more I felt very uncomfortable with the terms. I then went on the internet to search both Group Mayan and HSI reputation and no surprise I found very bad comments and complaints against them. I called the guy on Friday. He still said he would take care of my USA timeshare selling and shouldn't worry about it at all. We had to leave Mexico to USA on Saturday afternoon. I called a taxi on Saturday morning and asked to send us back to Group Mayan before we leave Mexico. I must confront them to cancel the contract in mexico. I really could not trust what the guy promise us for. After we arrived in Group Mayan, there were 4 employees individually interviewed us. They just wouldn't let us go. We were hungry and they did not care. We were in hurry to catch the international flight and the did not care. They still tried to convince me to stay in the contract. They even offered me $7500 package for the 4-week package. It's so rediculous!!! A $25, 000 package now can be sold to me for $7, 500? What a rip off!!! At that time I was so upset and said even it was free I did not want it. Finally after we were there for almost 3 hours, the last interviewer credited our money back to the credit card and let us go. By the way, they were so rude, rough, unpleasant to deal wih and to talk with. I remember the black guy was the worst person. He is definitely an evil person!!! I also need to mention that these 4 people were corperate personnel/high ranking staff for Group Mayan! I could not say what words they use trying to insult us and brain wash on us!!! After come back to USA, I contacted the company that was offered by Group Mayan and found it was not a real estate/timeshare broker. The company is in Taxas and just a advertising agency asking fees upfront. All you people please be careful not to buy any timeshare in Mexico (other vacation clubs in mexico were also crooks) and other countries!!! You don't have enough power to fight these bad people at all. So stay from them and be firm not let them to rip off your hard working money. Otherwise Cancun Mexico is a fun place for vacation.
