Query: hp ink cartridge

The ink cartridge, for an hp printer, which I ordered in December came within a few days but I didn't open the package until early February when the old cartridge ran out. When I opened the package I discovered that it contained the wrong cartridge. By then I figured it was too late to return the improper cartridge but, when I wrote a one star review, the seller immediately replaced the improper cartridge. I'm impressed and I'll be back!
