I did not receive my tiles C

Today, I was playing a Portugal match event on FC Mobile to get my tiles because I was about to complete everything and I had only one tile left, which was tile C. After playing a match, they told me to update the game, which I did. After updating it, they did not give me back my tile C. I went back to the Portugal event and checked the match; it had been completed. Please give me back my tile C!
