Can I get a refund after the Armani applet is delivered?

Yes, you can. Just communicate with the seller of Armani applet.

1. If the seller just clicked the delivery option and didn't actually send the courier, then communicate with the seller and apply for a refund directly.

If the courier has been sent, the best way is to reject the courier directly, so that the goods will be returned without any cost, and then you can just apply for a refund.
