Answer 3

What you CAN do is to tell your story... what happened to YOU. As long as you tell the truth, you are fine. Don't say things like, "Don't hire him; he is a thief!" Instead, say something like, "A week after the install, the granite cracked, and (he) has not responded to any of my requests for an inspection or a resolution."
Stick to the facts.

Answer 4

You definitely don't want to be sued ..... sewed means someone would be getting after you with a needle and thread!
