Thanks for your input and advice all
It's great to have a community like this to learn from!
I've been told by VC the seller was listed as a 'professional seller' and they let me return the item. I reported these issues immediately on the day I received the package, hope the seller doesn't try to dispute these defects. I'm keeping my fingers crossed for a smooth refund process. I'll keep you posted
In the first place this should be a matter for VC Quality Control.
If QC agrees with you, the seller should have no option to dispute your claim if the condition does not match the description given and the relevant parts of the bag were not shown on the listing.
You should have a good outcome - but brook no nonsense!
