Postegro Subscription Not Working – Urgently Requesting Cancellation and Refund

I recently purchased a weekly subscription with Postegro, but the app isn’t functioning at all. I urgently need my subscription canceled and the amount I paid refunded. This situation is unacceptable, and I’ve seen others reporting similar issues where they’re charged monthly even after canceling. Please address this immediately. I’m requesting prompt assistance in canceling my membership and processing my refund, as it’s unfair for Postegro to charge people for a non-functioning service.
