Used Cylinder= Bad New Cylinder Ordered

Today I got the horrible Brake Master Cylinder replaced with the used one I collected from eBay. Appearantly it is in worse condition than the one that was in there before. With the brand new Brake Master Cylinder I ordered, having not been correctly described, I therefore recieved the wrong one. I ordered a brand new cylinder online- the CORRECT one this time. I made complete sure with the seller first. I will need to re-sell the unusable new cylinder on eBay or the 924board. More updates soon!
