All reference to the seller has been deleted by me. I assumed when I looked at the package that the damage was to the top of the cover but the seller has informed me that the damage is to a piece sewn on the inside. Following his recommendation I unpacked it and yes the topside is fine and the damaged section is on the inside. He has offered me a discount if I want to keep it or he would pay for shipping back if I want to swap it out or probably refund. Think I will keep it and give it a try.
As they say when you assume like I did, that it was damaged on the outside without removing it from the package, you make an "ass out of" well you all know the rest. Might be almost classified as "fake news", sorry.
