Bought book series on kindle, book 3 missing

[Peachyscream]

Hello all,
As the title says, I treated myself to a series of books. Read 2 of them, and just checked and book 3 isn't there. I've gone back to "my orders" on amazon and its 5 books that come up on order history. HOWEVER I purchased the full series, so why isn't the 3rd one included? I didn't add each individually to basket, I clicked the option to buy the collection.

Now there's no option to contact anyone coming up for this purchase. It gives an option for return/refund but I suspect as I clicked on each book to find book 3 it'll come up as read and I don't want to return I want to read them!!

Any advice?

There should be the option on your Amazon account to ‘push’ books to your device, have you tried that?

Check it doesn't continue from the end of book two.

Thank you for the replies, will check both options 😊
