DewXP Not Working

I entered 12 matches of DewXP a few weeks ago and reached the XP cap. the next day and, over the course of the last two weeks, I have entered 65 matches of DewXP and have not received any in-game. the matches were applied on the DewXP website to my Xbox account and subtracted from my available matches. I have yet to receive any of my 65 matches and it’s been 16 days.

please help,
