Hi Mehim,
Sorry to hear this. While 5 hours is a long time to bot, that does sound quite unlucky.
Unfortunately, while it is actually OSBot who handle refund requests, I do not believe they list bans as a valid reason for one. Since botting is against the game rules, you use this bot (and all scripts on this site) at your own risk.
In future, i'd strongly suggest keeping sessions much shorter, using generous breaks and playing legitimately between sessions. For more information about bans and how to prevent them, be sure to give this thread a read: https://osbot.org/forum/topic/124429-preventing-rs-botting-bans-v2/
