JackpotCity complaint: Refuse to pay my winning or confiscated my winning

I been playing jackpot city couple years now depositing money no problem but for the first time I won 3500 last first week of may at first they confiscated my winning because I use my sister prepaid credit card. I explain everything and I admit I use my sister prepaid credit card pandemic time which the store that time where I buy the paysafe voucher was close. They asked me to send to them the koho prepaid credit card statement of my sister which I did send all what they asked then I got an email from them stating that my account is verified so login to live chat to ask about my withdrawal the customer service told me that this is the exact word I can advice to you that your withdrawal of 3500 is in our processing queue once it is reflects paid in your side it will be going to your account ending in @yahoo.com and once transferred to you you should recieved a email or txt to advice this payment has been paid to your account. And I asked how many days do u think he reply to me I can it should be paid to your account within 48hrs. After 3 I didnt recieve the payment yet I login to live chat and asked they told me my winning is confiscated and asked me again to send my sister ownership prepaid credit card so I was shock and disappointed coz I though I’m done with that thing since after sending all they asked they email me stating my account is verified. And of corse I sent them right away again my sister ownership koho statement customer service told me this is the exact word ty for holding I do see that we have recieved all the document requested from you and they have been approved… the payment method has been sent top our payment team to update…we are now waiting feedback from payment to advice on. After couple days I went to live chat another customer service they confiscated my winning. It’s so frustrating. I hope you guys can help me regarding with this
