Query: Terrible Customer Service!!

I bought my Lexmark Z42 last November. I was told at the time it has the LexExpress Warranty, so if it stopped working I could take it back to the retailer and Lexmark would ship a replacement printer to me. Well, it has had numerous problems in the last two or three months such as stalling during print jobs and paper jams and misfeeds. A couple times I tried to print and my computer froze and had to be restarted, etc. We hooked it up to my husband's computer and it did not work there either. ... This is the LAST Lexmark product I ever buy. ...Instead I have had the inconvenience of finding other means of printing my documents and photographs.
