Possiable to reset seasonal challenge?

When attempting the seasonal challenge “Because of bugged” I tried multiple times assassinating the elite at the bottom of the cliff. But I decide to give up but I came back after being away from my console and after coming back I restarted my mission and when did so I some how completed the challenge even though I didn’t even assassinated the elite. I was wondering if someone from 343 could go into my account and reset the challenge “Because of bugged” on my account if possible because I feel cheated and I didn’t get satisfaction from the challenge.
