We are a printing business and ordered some toner for one of our production machines. QuikShip Toner sent us the wrong part number, acknowledged they sent the wrong toner, told us they would email us return labels, and then NOTHING! Nothing for weeks! Nothing after contacting them multiple times about the order! This has been about 6 months ago and still NOTHING! Finally had to open up their cartridges and transfer toner into compatible cartridges just to get my use out of the $500 worth of toner I had ordered from them. Will never do business with them again!
