As there is no response from the seller you can immediately open a case under eBay's money back guarantee:

It's important to read the procedure carefully and follow the timelines. A case must be opened within 30 days after the actual (or latest estimated) delivery date. If still unresolved after 8 days you need to escalate it for eBay to step in.
p.s. There is a link to eBay's money back guarantee in every listing. As a member for 10 years, with 345 feedback, have you never even noticed it??
