Flutterwave task winner in week 4 of big brother naija 2022

I think there may be some confusion here.

Flutterwave is a payment technology company, not a task or a challenge in the Big Brother Naija reality TV show. Big Brother Naija is a popular Nigerian reality TV show where contestants, known as "housemates," compete in various challenges and tasks to win prizes and avoid eviction.

If you're asking about the winner of a task or challenge in Week 4 of Big Brother Naija 2022, I'd be happy to help you with that. However, I would need more information about the specific task or challenge you're referring to.

Could you please provide more context or clarify which task or challenge you're asking about?
