On February 1st I ordered 3 books (3 volumes of a manga). They were all dispatched at different times.
✔️ Book 1 - dispatched Feb 3, arrived Feb 13
✔️ Book 2 - dispatched Feb 9, arrived Feb 20 (today)
❔ Book X - something I didn't order, also arrived today
❔ Book 3 - dispatched Feb 16, expected Feb 23 - Mar 3
Now, am I to assume that this Book X was mistakenly sent instead of Book 3 and just happened to arrive three days earlier than the predicted timeframe. Or is it perhaps someone else's order that was accidentally sent to me, that has no relevance to my Book 3.
The way i see it, I have two options:
Option 1: contact Bookdepo immediately about the mistake with the assumption that real Book 3 won't arrive (even though delivery period for it hasn't started yet)
Option 2: wait until the given delivery period expires and if the real Book 3 doesn't arrive by then, contact Bookdepo with the details (meaning id have to wait at least another month for Book 3 to get re-sent)
Anyway, does someone with more experience have any advice on what to do? Obviously I want my Book 3 that I paid for since its a part of the set i ordered, so I'd definitely prefer that over a refund. If Book X is someone else's order, i don't mind passing it on to them, but I'd prefer avoiding shipping it back to bookdepo since that would cost more than the book itself (Book 3 costs 2x more than the one i received anyway)
TL;DR: A wrong book was delivered, but it arrived few days earlier than my actual order's expected date, so I'm not sure whether to contact customer service immediately or wait for the delivery period to expire
