May's Xbox live quests and reward concern

I've completed all the objectives this month and it's stating one is only 50% I'm trying to have it fixed so I don't miss it on my exclusive Fortnite reward for quest completion this May for live gold.

The promotion ends in a few days. I want to be sure I'll be receiving my Fortnite reward or I will be talking my business elsewhere. I've had too many issues in the last few years with Microsoft and if this is an indication of how my progress and rewards
are to be handled I'll prefer to take my business to Sony and start buying their product.

I have not recieve my reward for April's quests and I cannot see the progress for May's quests

 

When do we receive our rewards for may's xbox quests?

I was told by a microsoft support worker that if I posted asking about the specific date We would be granted with our rewards from completing May's xbox live quests that I would get an answer here. So if you have an answer, please reply.
