That's lousy. I get the impression that they know you or are at least familiar with them. That makes a big difference your reaction.

I can understand it happening once, but for them to do it twice!!

My first thought was that an employee was going to sell it on an online auction site.

You should have had the employee bring it in and not felt bad about it.

Also, I understand that you are not asking for a$2 giftcard but for them to cash-in the gift card already in your possession. (I read another reply that misunderstood your post, probably reading too quickly.)

It would be nice if they got that poster and gave you a call since your number is probably still on the back of it.

I can't say that I see much resolution on this other than through the local manager. Good Luck.
