It's encouraging that MrRingo usually pay up in the end. As Quincunx says, keep chasing both them and the Curacao authorities and hopefully you'll get your winnings before too much longer.
Update 2 months later; MrRingo still doesnt pay. Support does not reply. Their sportsbook regulator Curacao sent back one unsatisfactory e-mail, I sent 3 more, and no answer. I am very dissapointed also from Curacao. This is not a normal regulator. If it was a normal regulator, MrRingo wouldnt exist anymore. But MrRinog exists, something more accepts deposits.
Thanks for updating us anyway,Illina.I note that MrRingo's odds are still listed on OddsPortal.I am guessing that they are still pulling in some new accounts/new money.Since you seem to have hit a brick wall with the Curacao regulator,the only route that I can think of is the link provided earlier in this thread by BMR.You could also try googling and contacting the people who they advertise with,the odds comparison websites that their odds are listed on,etc,although this may not get you the money that they owe you.
I notice that MrRingo seem to have a very active Twitter account (twitter.com/Mrringo_com). Have you thought about posting details of your experiences with them on Twitter yourself? It probably won't help you get your winnings, but it may well prevent other players from betting with them.
Update: After 3 months, I have an answer from MrRingo The Cheaters... Here it is:
Good afternoon Mrs.Saradinova
sadly I must inform you that a strong influx of users coming from your current country of residence have been identified as scamming the system itself. Due to this we regret to inform you that all bonuses and all the resulting winnings from the country itself are rendered void. The initial last deposit will be reimbursed and you have full access to it from this point onwards, but no more bonuses will be assigned to these countries. The deposit amount itself will be on the account. We apologize for any inconviences this may cause for you.
The sum of the reimbursed deposit itself is 100€

What a silly reason for confiscating winnings. Why accepting deposits if not accepting players. Something more, I have screenshot of the previous terms and conditions.
But I have good news- I am in correspondence with Interpol about computer frauds. If Curacao doesnt help, police will...
