Customer service issue.

[NewChief]

Okay: my wife has a store (wedding crap). A girl won a raffle and got a $50 gift certificate. She ordered an item from us and spent some other money as well. All good so far.

Our employee went back and forth with producers of item (there is a proofing process) but neglected to give final approve to produce item because she forgot prior to going on vacation and then forgot when she returned from vaction. Thus item was unmade for 2 weeks. We had told customer we would have item for her in two weeks. When we found out item was not approved by employee, we paid rush fee to have item made quickly. Sadly, this all happened around 4th of July and item was not made for 3 More weeks (5 week total). Customer also dropped invites off at store so we could apply item to them for her. We then paid $90 to have item overnighted (mind you the customer paid nothing for item because was won in drawing) when it was made. Unfortunately, item was still not made, and her deadline (and limits of her patience) for sending invites was reached, so she picked them back up and sent without item.

Item arrives next day and she picks it up. She has now bad mouthed our business on Facebook.

Now, initial problem was definitely our mistake. We then went above and beyond, IMO, to try to rectify issue, especially considering we were getting zero money on this transaction.

My question: just let it go? Or should we try to let the customer know the amount we spent trying to rectify situation? We've already apologized repeatedly and offered her husband some free shit when he came to pick up item, which he declined.
