You mentioned in your blog the items supplied DID NOT have the park light facility as described in the advert.
If you paid via PayPal, then surely that is cause for a claim as being "not as described"....part from many others issues about not fitting. Note that you have 45 days (IIRC) friom date of purchase to lodge a claim.
Basically, if it is not what was advertised, then it is the
wrong goods.
Being able to make a claim for "wrong goods" is one of the benfits of PayPal transactions.
Or even explore a Dispute claim thru eBay.
Do it thru eBay, not outside the system. Tehn they have a record (esp. re timeframes mentioned above).
I have had success with refunds for
wrong goods supplied / did not fit as claimed by seller. Good luck.
p.s. you've got me worried about my spare pair in the cupboard....excuse me, gotta go check......
