So update on my situation, the status has gone from pending approval to 'error'. Upon contacting the support today again they responded with
"Unfortunately, your withdrawal cannot be released at this time due to restrictions identified during our review.
Even though I can't disclose the exact specifics, I strongly suggest that you carefully review our T&C to understand the potential reasons for this restriction. You can find our Terms & Conditions on our website
https://earnbet.io/terms."
In total, around 2500 euro that I have won legitimately on sports bettings has now been confiscated by them. I would suggest others to be very careful with this casino.
https://imgur.com/a/x0AEoeYI understand your frustration at this moment even though I haven't quite experienced anything like this before, but I can only encourage you to be patient and not give up hope or lose confidence in this platform because there's always light at the end of the tunnel.
An error message definitely means your balance has been zeroed perhaps due to reasons of having more than one account created from same IP address, device footprint, using shared VPN to access the site among other reasons.
Maybe you didn't comply well with your KYC requirements or you funded your account with an address associated with multiple users, but the only thing you can do is to not give up hope and try to submit a formal complaint with evidence to the sub-licencing authority.
I can't help you destroy the reputation of earnbet.io but I can pray for you to find a resolve to your pressing issues because you are a customer and if the customer is always right by standard, you should be given a better response than being directed to go read the TOS of which may be too bogus to breakdown to understanding.
