Mexico Resorts

We were sold the voucher with 2 packages:
6 days 5 nights in Mexico with the commitment to attend a sales presentation. We were offered 5 days 4 nights instead. We redeemed this part successfully.
As a bonus, we got 6 days 5 nights in Costa Rica AI. Called 2-3 times within a year. Costa Rica is never available. Instead, 5 days 4 nights AI in Mexico / Dominican Republic is being offered with the additional reservations fees, etc.As we proceed with our reservation request, our contact representative is not getting back with the confirmation that the reservation is confirmed (waited for 10 days before writing this review).
This is a scum company.
