There is no reason to think that the certificate is not a gesture of goodwill from them, it would seem inappropriate if it were only given to you as a bribe, to get you to keep damaged merchandise. You did not purchase a used bag - elux, is not ebay - you expected brand new bag, period, end of story.
You paid too much ($800, right) to make up for the used quality - $50 GC is paramount to a little over 5% off that bag - sheesh, we all know that if that bag made its way to a second chance store due to it's used/defects it would be offered at 30%-40% off.
Send that bag back and use your GC.
