I've already stated that I haven't registered so many accounts; there's no need for it. I haven't claimed any bonuses or promotional rewards either. There are issues with Shuffle's management itself. The fact remains that I can't withdraw the funds from my account.
I see that your complaint on CasinoGuru is now available for public. Let's see their ruling for this issue, suppose they goes far and touched the multi-acc issue instead of just stopping at the VPN. I am sure Shuffle is more than happy to provide all the supporting evidence of their findings to the arbitrator.
