Heya, i'm sorry to hear this. Unfortunately bans do happen, and there's no telling when. I've maxed an account (and I know others have too) without recieving any bans, whereas some people get banned faster. There's also no way of knowing whether you were banned solely for this script or as a delayed ban from another one. There's no way of predicting (or, for that matter, preventing) bans that we know of, so it really is just random and a risk you have to accept when using any script!
While it's not my choice who receives refunds, and normally requests are denied if the reason is bans, here are a few things to consider for next time!
Firstly, if you haven't already, give this page a read: osbot.org/forum/topic/45618-preventing-rs-botting-bans/
In future I would recommend against botting on accounts you care for, namely your main. I would suggest botting sessions of <45 mins with perhaps equal or more breaks.
Finally, here's a link to the page where you can submit a refund request, should you so wish! https://osbot.org/forum/announcement/50-payment-issue-guidelines-read-before-posting-refund-template/
