I had recently purchased an MX master 4 logitech ebay, after much issue with shipping -seller sent package under wrong name of Erin Corbin leaving me unable to pick up from FedEx pick up and leaving my item in Fed Ex package for two weeks- during which that seller pulled their listing and is arguing about refdunding me even thought the item I was sent does not match the original listing. To add more oddity to the situation I am unable to find anyone I can contact regarding this disput now that it has been resolved. What do I do? Is their someone I can regarding this purchase out of staples store next state over or I am just screwed? I have been using this site for years and I am somewhat savy with the ins/outs of its operations but am unable to get any results on this issue, what do I do next?
