Left black streaks on printed pages!!!!

Item did not perform properly. Would leave black streaks on all printed pages making them unreadable. I'm also not finding an easy way to return the item for a refund. I find it hard to believe that this is considered an "Amazon Choice" for a toner cartridge. I understand it is a cheaper version tha an original dell cartridge, but there should be a refund available if it doesn't perform properly. I would not recommend purchasing this product
