Did you approach the seller for a refund??
No, for various reasons like losing the ebay sellers details (!) and because I need my car for getting to work I couldn't take it off the road again until recently. By that point of course they were well and truly cream crackered.
I was not too concerned as I only replaced them quickly for the MOT last year and always intended a full rebuild this year (now done, all Alfa parts and not too expensive)
None of this is helped by the appalling state of the roads round my way and too many speed bumps...
