If you really want to get a Consumer Affairs issue resolved take it to the Consumer Affairs Dept in every state of the USA. Then both sides can have a fair hearing, and one party wont be an anonymous social media account.
I believe UR is in Georgia, USA. This is a link the Consumer Affairs Dept in Georgia, as far as I can tell. It looks like it is not hard to contact them and get your complaint investigated and resolved.
The Georgia Attorney General's Consumer Protection Division is the consumer protection agency for the State of Georgia. We help protect consumers from un

I would like to suggest that UU admins consider a process that is fair to both sides when there is a complaining thread like this so that UU is not just turned into a board to badmouth selected sellers to the advantage of other sellers.
If members feel the need to use UU as their personal Consumer Affairs Bureau, there should be a fair and open process in the UU rules so both sides get the opportunity for a fair hearing and members do not sully the reputation of UU with irrational complaints. If it is too hard to develop a process the simple thing to do is to allow members to use the reporting process to get some fair mediation within the time resources of the admins and if necessary, delete the thread.
Members should be able to vent consumer affairs issues, but in a way that is fair and adds to UU credibility instead of eroding UU credibility. Fairness requires full disclosure of names and business hour contacts for both parties, not just one side. Those who are afraid to complain and provide their real names should be directed to the State authorities which have resources to keep names and addresses confidential during an investigation.
