Damn right, anyway TS I've been in your shoes, I bought a mouse from a shop but realised something not right with the roller (a little clicking noise when roll, which was no biggie). I've demanded a 1 to 1 exchange and to my surprise they denied and instead offer a normal warranty process, but luckily the process only took about a week so I'm okay with that.

Seriously, go to SC for advice, bickering here won't solve anything, worse...b00n is watching you. :|
