Great Holiday Club — they keep asking for more money

When we purchased the package we were promised immediate booking and the choice of hotels were rwally good. But once u actually pay them and the list of hotels being provided is completely different from the one promised.
Secondly i haven't used their service till date and have paid 60000 to them and when i asked for a booking they started asking for another 6000 for a hotel room for 4 days when the original price is worth 1200. And when i asked for a better option they don't revert.
It's a scamm i am worried if i pay a single penny more they might just stop respondi g
