Hi,
Regarding the OP about paying twice, please open a support ticket, our Support team will be able to see which payment provider processed the payment. Unfortunately, we can't do more than that so you would need to contact the payment provider directly and get reimbursed the second payment amount.
About GrimeFighter running for 65 hours, that is definitely a bug. GrimeFighter should not run for more than 6 hours. This is a known issue and we are working on fixing it now. It's not clear how long until the fix will be implemented. The choices are to either give us a few weeks to fix the issue (which we would greatly appreciate) or you could request a refund. Please do accept our sincere apologies for this negative experience.
GrimeFighter team
