You should complain to Amazon UK. They will mail you a replacement copy (and you can probably get to keep that damaged copy without mailing back). Just remember to tell them to pack the book properly because their previous packaging damaged the book. Or you can choose to refund.
As for the binding. It's not very durable, even if you receive a pristine copy from them. If you open the book too wide, the spine will crack again.
