Undelivered Order and Refund Issue

I placed an order with Bagallery, but my order has not been delivered yet. I have been trying to contact their customer support for the past 2 days, but they are only responding once a day and my complaint has still not been properly registered. I want to cancel the undelivered order and receive my refund urgently. Despite repeatedly contacting them, they are not taking proper action or resolving my issue. Please help me resolve this matter and ensure that my undelivered order is cancelled and my refund is processed as soon as possible.
