eBay provide buyers with the tools to resolve your situation. The Resolution Centre:
https://resolutioncentre.eBay.co.uk/
Follow the instructions carefully and escalate to eBay after 3 business days after opening the case if the refund is not started in the meantime.
eBay will force a full refund.
Keep what you have received as you may have to wrap it up and post it back to the seller at the seller's expense.
Be sure to open an Item Not As Described case, NOT an Item Not Received case.
You have received something. Only part of what you ordered.
The seller can defend an Item Not Received case if they can supply tracking showing you have received ‘something’.
It is better to receive a full refund than start a new transaction.
