The customer service I received today was completely uncalled for and extremely rude. They sold me an empty cartridge which I returned immediately for replacement. They declared there was no way that could have happened because the empty cartridge from THEIR box was not theirs because it didn't have their label on it (which obviously they forgot to put their label on the cartridge which had not been filled yet). When I became visibly upset at this response, they said I was attacking THEIR integrity and stated they did not want me as a customer after I had been buying ink regularly from them for 7 months with no problems. They do not deserve ANY stars. I have NEVER been treated so rudely. As a retail manager for 7 years, we always treated the customer with utmost respect "the customer is always right!" I was stunned with the treatment I received and do not recommend you take a chance with having the same problem. IF you choose to do business with them, make sure you OPEN the box before leaving the store so they have NO recourse such as what I experienced!!!!!
