Not received OFW shards

Hello, I've completed the One Famous Wookie event but I'm 25 shards short for the 7 stars. I didn't realise at the time and assumed I'd find them somewhere else but it's been months now and they aren't available anywhere.

It's now blocking me with other events as I need Chewbacca to unlock several other characters.

Please can you help me. My ally code is 786-221-558.

Thank you
