I think this is the case.
In my case, I actually made a deposit 1. WELCOME bonus (100% + 1 day 20FS x 10 days total 200FS) and 2. What anniversary 5 x 5 bonus (25FS a day until 4/11 every day) I tried to use something that is available), but for some reason the bonus of 1 is no longer available after 2 days.
The bonus of 2 can only be used on the day and cannot be used from the next day.
Therefore, I contacted the customer and confirmed the reason and cause, but
"It looks like the bonus you're talking about has already been used."
Only one word.
Moreover, the email I inquired about in the morning was returned the night after about 12 hours.
At that time, I asked the question again, but there was no reply.
In my case, I had already submitted all the identity verification documents before and after playing, so my identity should have been clear, and I wonder if it's too stupid for a highly rated casino. I felt that.
I don't care about one or two of the bonuses, but if there is something wrong with the above measures, I will not do it properly if it is troublesome, so personally Judging that it is unreliable, I will refrain from using it in the future.
After all, if you play, you want to play comfortably, so you don't want to feel negative because it doesn't matter.
I hope that those who have seen it will find it helpful.
