I made a withdrawal of 0.603ETH since 2023.06.14 but not recieved yet.
And there's also 0.7ETH left in my balance.
But after 20 days they said "Yes, sometimes it takes more even 6 months. I am forwarding the info to the relevant team to check again. Please wait with patience".
Do you think it's normal for a sportsbook to investigate for more than 6 months?
According to your image, Blackjack.fun stated that some investigations could take up to 6 months they didn't say yours will take up to that amount of time.
But, to be sincere I think that the duration for an investigation is too long, I would agree with one to two months or at most three months but once it exceeds that I will raise up a scam accusation thread against them because I can't think of what will take them good six months to investigate.
For now, I think it's best you explore the gambling board more read through ANNs thread and select a more reputable casino, don't just go for their duration in the industry alone, their responses to customer's complaints and how issues are resolved should also play a big in your selection of a casino.
