Forgot to Enclose Card and to Keep Receipt

This is my first year doing the Secret Paws exchange, and I made a couple of mistakes.

First, while I did get a tracking number on my receipt, I forgot afterwards that I needed to keep the receipt. All I have is a photo of the gifts before I packed them.

Second, I neglected to put a card inside with my info. I did however write my address on the package.

I mailed my package on December 13. Surely, it would have arrived by now?
