Every major gambling site will certainly have fast support and the staff will be placed in various fields and if a problem occurs, of course, the support staff will respond faster to solve the problem, I think there are no serious complaints about this so that's all OK, I'm like you, the problem was resolved in just 5 minutes, meaning their support is very responsive to every client who has a problem.
Fast support is good to help service becomes more reliable and friendly. People will look at scam accusation, complaints or compliments on support to see how one service looks like. It is good to know your problem was supported quickly and resolved very fast as well.
I think it's only natural that the delay of the withdrawal is delayed a little maybe it's because of the slow confirmation of the block or indeed something else so it can't be faulted that the direct support will wait a little more at some point and it will definitely be sent to the withdrawn wallet.
Withdrawal requests on big services usually will be handled automatically. Only big withdrawal requests will be considered deeper and might go through manual processes that take longer Pending time. When such big withdrawal requests are approved, transactions will be broadcasted immediately.
On big gambling sites, withdrawals are almost immediately.
