I ordered a set of toner - 3 color and 1 black. They sent the wrong black. I couldn't figure out what was wrong, because it looked exactly like the starter toner that was in there. I just kept on getting an error message. I went through three Lexmark tech support agents, before someone could finally figure out it was the wrong toner.
In the meantime, I got so frustrated I bought another from Staples (based on the number on the box). So that one failed too. So, now I have 2 opened toners I can't use.
They refuse to fix their error. I know I didn't go around their website looking for color and black toner - I bought it all on the same page.
They clearly couldn't care less. I won't be back.
