Ordered 5 ink cartridges for my plotter in July. Package arrived with 2 ink cartridges. With orders often coming from different places, I figured the balance of the order would arrive, no worries. A month plus goes by and I realize I never received the balance of the order. I follow up and BDI customer service says, sorry about your "shortage", we'll check it out. Another month goes by and I follow up. They say, because so much time has gone by, we cannot do anything. Then they say the order was fully sent according to the weight of package (0.7 lbs). I check the weight of the two cartridges I received and based on their weight (7 oz), if all 5 had been sent the weight of the package would have been about double what was recorded on the freight receipt. I send photo of two cartridges to BDI to prove it and they ignore it. THE WORST CUSTOMER SERVICE EVER! I basically got bilked for more than half of my order.
