I sincerely apologize for the delay in getting back to you and for the inconvenience caused by your experience with the bonus buy rounds in Bonanza Billion and Penny Pelican.
After reviewing your case, I can confirm that the stuck bonus rounds were closed unexpectedly. As a result, we have now compensated the amount directly to your account. Please check your balance, and let us know if you need any further assistance.
That's a rare scam complaint to resolve nowadays that I can see/read on this board. If this is just an honest mistake from the winz then complaining about any unfair treatment toward any casino is not bad at all, thus this community here serves its purpose.
