will it impact my case that the PayPal advisor changed it to a ISNAD?

Definitely not.

Disputes get changed all the time, either due to lack of knowledge from the account holder, or an error In judgement. By no means does It Imply an attempt to falsify the claim.

To be honest, I feel like they can’t refuse it, simply cos of the photo evidence.

The nature of the photo you have In your possession, Is a very solid piece of evidence.

Personally, I don't see the grounds on which It can be declined.

Thanks for all your info!

You're most welcome.
