Query: Not what I ordered

I ordered, per web ad, a Sylvania branded product - was shipped DAMAR brand which was available elsewhere for less. Product did not function and did not fit well - about a inch diameter off. Gave up and ordered a complete new fixture which used a GE product. The main beef I have is that the vendor did not ask if a substitute brand was OK to ship.
