ToysRus selling used Good to the public

ToysRus Pavilion are selling used Good to consumers. I have purchased a volkano tablet for my little 1 only to open it and have it with scuff marks and scratches. I arrived a the store to return the product for a new 1 and it was the same. I asked for my refund and Anand/kaylin both store managers refused to do so. Anand has no customer etiquette and was extremely rude. It's the 2nd time I've dealt with him. I have left the tablet in store as they refuse to return my money. Head office have still not returned my call.
