Hi,I'm Zoey and I'll be assisting you. I'm reviewing your question now.
That website is not active and, according to its WHOIS information, has never been active. Please provide me with a correct website so that I can find where you'd go to cancel their services.
Actually, it's ozlottoservice.com. You can cancel your account with them on their website by going into your user profile and then to "subscription management." That should be all you have to do. If you can no longer log in, you can contact customer service for them here and cancel your account and tell them to stop billing you.
If customer service doesn't resolve that for you, you would have to contact your bank or credit card carrier and report further charges as unauthorized and/or close the account and open new ones to stop the billing.
Just checking in to see if you need more help or any clarification of my answer. If so, please reply here on this question thread.
