i had seen ads for cartridge world. i thought i would try them on lincoln road on miami beach fl. i had a $450.00 hp printer. i had a job to do i went there - it took 3 trips to get my cartridge refilled. it would never work - i called the headquarters because they are a franchise. the head office said it means they put the wrong powder in and it broke something and that the franchise should fix it. i left it with them and finally got it back and they wanted $350 to fix it - and thery were not paying for it. i called headquarters and they said they could not force them to fix it. my machine was a big paperweight at that point. it was obvious the owner did not care at all and did not even make a pretense if caring - or of trying to fix the problem they caused. i think they are rude and do not deserve to have one customer. beware!! i had to buy a new machine!! over $300 and my deadline was late. one of hte workers bumped into me at the grocery store and confessed that the same thing happens once in awhile and that the owner never refunds the money. he acts like he is god and in charge. read more
