Self-publishing loses it s appeal

The saga of publishing a paperback copy of The Queen's Letters goes on and on.

After receiving a proof copy I have redesigned the inner content, and thought all was done. Set to Publish. Back comes an email saying I have loaded the barcode in the wrong place. So I redesign the back cover, which means rejigging the whole back, spine and front cover and carefully re-position the barcode and send it off. Now they are telling me the barcode is not there. What do they want? I can't stick a real barcode on the cover when I'm working online, now can I? It seems an impossible task.

I don't recall having this problem with Createspace. And now this morning they have decided that I need to update tax information because I have relocated from Createspace to KDP. Suddenly self-publishing loses its appeal.
