I mostly low-roll on slots now, usually I'm playing for comps. If I have balance remaining I will increase stakes to finish wagering. I rarely play slots on my sportsbook where most of my balance is since they banned me from their slots tourney in an *****-ish way (I placed 2nd, but they banned me from it and didn't even give me the prize). But yes I USED to dabble in very high stakes.
Are you trying with PC or phone?
If its not possible from both then please go to your bank branch and ask them to send you the pdf file. Most banks give it the same day.
