I had an issue with this person's dispenser and attempted to contact them thru SOG channels on Telegram and Discord. There has been no response. I would not suggest buying from this user. If enough time passes and there is no communication I will leave this user negative feedback.
It looks like you overpaid by a pretty hefty amount. The honorable thing for them to do would be to repay you at least 90% of the overpayment amount. I have always reimbursed anybody who overpaid for one of my dispensers.
