Maybe there is something wrong with your betting activity. This is why they have asked you to complete the KYC verification quickly. You have gone through similar process on a
different casino a few weeks ago. Did they ask you to complete the KYC verification during withdrawal? In which sports event you place your bets? Usually, KYC verification takes long time to complete when proof of address and source of funds verification is required.
I only had a few bets on NCAA men's basketball. And I lost $150 on them. Again, I then placed another $150, didn't bet any more, and about 10 hours later they asked for my documents. Nothing unusual on my part. I bet in many places, and I never have any questions about them.
