Complaint Review: Grand Miramar Club and Spa - Puerto Vallarta Internet

In early February, 2011, I filed a dispute on my Amexican Express card account and my Bank of America Visa.  Recent events, as outlined below, have indicated that we were fraudulently duped into buying an interval ownership at Grand Miramar Resort and Spa by a Mexican corporation known as Disyga, S.A. DE C.V.
On August 12, 2010 we visited Grand Miramar Resort and Spa, owned by Disyga, S. A. DE C.V.  We toured the property and over the course of about 5 hours we were offered a preconstruction membership for a one-bedroom master suite.  The membership is for 4 weeks usage per year at the resort. 
During the course of our negotiations, the sales manager offered us financing through Bank of America Visa with an introductory rate of 2.99% for the first 7 monthly statements.  This was the first of many very attractive features of the purchase but the most important was the guaranteed buyout of our timeshare at Hacienda Del Mar in Cabo San Lucas, MX for the written price of $24810. Initially, we decided to put down $30000 on the new Visa account (plus $900 foreign transaction fees).
The sales person an American named Jerry Forney made mention a few times that Bank of Americas presence proves legitimacy in the sale and that most of his customers take advantage of the low cost funding.  I must admit that I was fooled with this key confidence builder.
Also, we were required to buy a membership in Highend-Rentals (which is non-cancelable and non-refundable) in order to pay us the annual rental income of $5600 per year for 10 years that we contracted for, as well as the buyout of our Cabo timeshare.  We paid $2950 for that membership.
 Overnight, my wife and I felt that the deal might be too good to be true.  I did some research online and found no negative postings regarding Grand Miramar Resort and Spa.  But we decided to return to the property and change the negotiation, which left an outstanding balance of $16245.  We were concerned that the buyout of our timeshare would not happen quickly enough and we wanted to hedge a little in order to encourage the seller to send us our check for $24810.  Our assumption was that if the buyout did not occur within a few months, we could unwind the down payments we made through Bank of America for $10000 and Amex in the amount of $2172.45.  
So, at the time, we were made comfortable that if we had free and clear title, we could expect our buyout check in the mail within 30-60 days.  I emailed the documents to Grand Miramars real estate broker Highend-Rentals within 4 days of returning from our trip.  I was reassured by phone calls and emails that all our paperwork had been submitted in perfect order and we could expect the $24810 as promised.
In mid October, 2010 I received emails, letters and phone calls from the legal and collections department manager Cesar Mendez that we must either payoff the balance owed or be foreclosed upon and lose our down payment on the property (see enclosed documents).  He even offered us a discount to honor the transaction and lowered the balance to $14945.40.  We began to feel very uncomfortable and I wrote a demand letter requiring our buyout first.  After that I continued to receive phone calls and emails that all was still OK.  They again promised that should we fulfill our obligation to pay off the balance, we would be sure to receive our buyout any day soon.  They emailed a credit card authorization and my wife and I decided to stay the course and charge that amount to my wifes Visa on Oct 26, 2010.
On December 15,  I received an email from a broker in Texas Royal Sun Resort Resale that a corporate buyer was ready to go to escrow and that there were some fees that they were willing to pay.  Those fees would be added to my sale price in order that we would net out our contracted amount.  Only catch was that Royal Sun wanted me to pay the escrow fee upfront.  Right then, we began to lose complete confidence and referred the matter to our attorney.  His advice was never send any money in advance and research and demand to know the identity of the buyer.  At that time, with an online search, I read complaints from Americans and Canadians that had claimed they were scammed by Disyga, S. A. DE C.V.  and Grand Miramar just as I am reporting to you above. 
We still would love to receive our buyout but have no remaining belief that it will ever happen.  In as much as we were guaranteed this in writing (see enclosed documents) Disyga, S. A. DE C.V.  and Grand Miramar Resort and Spa have defaulted on our contract and we wish to charge back our credit card payments made to them.
