I'm not really fond of Sinclair. I did many shops for them with no problem. I did one where the location did not score too well and the client disputed it.
I did not know any of that until after I called when I noticed I could no longer view shops. They took away my ability to do shops ( I am still registered with the site, just can't view or be assigned shops), did not pay me for that shop, PLUS did not pay me for another shop for the same client that had taken place the month before and had not been disputed.
I am still called regularly though by a scheduler to do a shop 90 minutes away that he can not get anyone else to do.
