Atlantis Gold Casino - Non-payment, unauthorized transactions with my credit card

Hello. Thank you for hearing my complaint. During latter October, early November, 2015, I decided, for convenience, to play a few dollars of online slots. I selected AtlantisGold because they appeared to be a reputable online site. I went through the verification process and was approved after submitting the required documentation. However, I should have researched the reviews more carefully because I find the reviews were correct in terms of non-payment, Atlantis not keeping their word and non-responsiveness. On November 6, 2015, I won $900, played back $50 and was due a balance of $850. Every since that time I have been going back and forth with AtlantisGold regarding the payment. I was told it was take 2 to 4 weeks, so I waited. When I did not get a response after 4 weeks, I inquired again. I received an apology and was told the payment would be forthcoming in a few weeks. I never received any communication from Atlantis. On November 13th, I played $20. In checking my credit card account a few days later, I noticed my credit card account had two (2) $20 debits. In doing an accounting of transactions on my AtlantisGold account and my credit card account, I found this was a duplicate $20 transaction that I did not authorized. I contacted my credit card company and a dispute issue was submitted. A week later I received a $20 credit from my credit card company as the dispute was found in my flavor. During early January, I, again, contacted AtlantisGold regarding the $850 payment and was told it was being investigated due to the chargeback. And they wanted to know why there was a charge back, want an explanation and documentation. I sent them any explanation of what had happen and a copy of my charge card statement showing the duplicate. (My AtlantisGold account shows that I only played $20 on day, which is accurate. I have inquired twice regarding the status of the payment and they never respond. In addition I received a phone call late one night from my credit card company stating fraudulent transactions were being submitted against my credit card. My credit card had to be cancelled. The interesting issue is that AtlantisGold and their processors were the only merchants I was using this particular credit account with. I feel that my credit card information was compromised and fraudulently used due to the handling of their processors. I asked for my payment to be mailed as I do not feel secure providing them with another credit card account. I am very disappointed with AtlantisGold. If they cannot payout winnings, they should not be in business. Any assistance you can provided would be greatly appreciated.
