I attempted PEB today seeing as I don't think i had any other option, and I don't think that my agent cared enough to check. Refund or replacement was offered within 5 minutes of chat.

Well done.

Evidently, the rep didn't bother at all to check the nature of the Item against your claim for missing goods.

Also, would it be safe for me to begin a return process or wait for refund to finalise first?

Are you planning to return the other Item that came In the same shipment as the jacket?

Yes I am planning to do that.

Then It's fine, you can return It whenever you please - It's a legit return.
