bux.to

A PTC site called bux.to has been running for sometime now and many investors have paid many $ to earn some money back. In the beginning things were looking good with people being paid within bux.to's "terms of service" 30days for premium members and 60 days for standard members. Now there are people waiting for upto 12 months to be paid and they are not small amounts of money. I am talking about 10's of thousands of dollars. My claim alone is a 5 figure sum and I have been waiting in excess of 7 months.
The company is registered in the Dominican Republic. What options are there?

Thanks
