After being premium seller on flippa for many years, I see many unfair negative feedback left on sellers profile. According to flippa rules and policies, Buyer are aloud to leave false negative feedback as they wish. If you contact flippa and explain the decision, they will ignore your request and keep closing the ticket.
In this case, the buyer did not pay his own hosting and then blamed the seller because the site was down, leaving a negative feedback. ( feedback are really important on the seller profile! )
Flippa staff accepts to leave a false negative feedback on the seller’s profile even tho its proven that the buyer did not pay his hosting. By not paying the hosting the site was obviously down … (buyer’s fault!)
