Query: spray pump doesn't work

Spray pump doesn't work. Also this is the first time I bought this cologne, but it does not last very long, after 3 hours can't smell it at all. The bottle had some weird residue on it, that came off with water and sponge. All of these things lead me to suspect this may be a counterfeit knock off. No way to return because Amazon doesn't allow. This will be the last time I buy cologne from Amazon!
