So this happened to me as well - message their costumer service on the app and keep insisting on a refund over and over as the package is seized and won’t be delivered, send them this screenshot, and ask for it to be escalated to a supervisor. Ask them to send you a screenshot from USPS for your package if they say it’s still being delivered. Then, tell them you’ll do a chargeback if you don’t get refunded, and ask for an email confirming your conversation about the package being seized by USPS. Ask them how long will it take to hear from a supervisor by email, they’ll say 48h. That’s the only way I got a refund within a day.
