I tried to sort it out and instead got a rude PM saying that the seller wouldn't refund me money due. I took the next step told to me by the admins by posting it public.
You can find many reviews in this section about online retailers and there are many good and many bad comments about them.
If you can type something bad in a review section about a retailer then you shouldn't be allowed to post the good about a retailer as well.
Normally people would leave bad feedback and be done with it which I had considered but yet then LeGros would just leave me retaliatory negative feedback.
Instead this allowed LeGros to come in and make his own point of view and people could make up their own mind.
And by you saying that posting this is published slander and I could get into trouble, check the Better Business website. They have a list of "bad businesses".
