Missing XP and rewards 1-49 horde

Does anyone who if we will get back the rewards when there was an

error code after finishing a1-50 horde . This happened to me twice. Will will get those back?

I’ve had that error a few times already, but I’m still waiting on XP & Cards for JD & Lahni that I have yet to receive from 10/5/19 which is a week ago.
