Depop dispute is a little different now

The seller got back with me before depop. Depop still hasn’t repsonded. Even the way you open a dispute is a little different now. I hope this doesn’t affect me getting a refund. Something I ordered has like a bleachy discoloration on it and I’m hoping I’ll get a refund. I’m afraid the seller is going to get rude with me. Do I report them if they get rude?
