Don't worry about that, as far as I know they are very responsive in solving user problems, it just takes a little patience for them to solve your problem, I hope representatives from jacksclub who are active in this forum will immediately see your case and solve it immediately, come back again to see your post in the thread This is because they may reply and respond to your complaint here. At least you provide your account details so that the problem can be solved immediately by their representatives on this site.
I think the problem is in his password because if we checked his username on the site then we will find this https://jacksclub.io/?modal=user&user=Mandie . Assuming that it is his account, so he did nothing wrong when typing his username, that's why I guess he made a mistake when typing the password or he may forget something. By the way, forgot password seems to be working fine for me, as long as we type the right username/email, we will receive the email to recover our password. As long as I know Jacksclub has active telegram channel/group too, so maybe he can try to get information in the telegram group/channel if the support is a bit slow in responding his message.
