Spam from QMax

It happen that few day ago , i m going through my email which been label as ADV , my gmail filter will actually filter out those email start with [ADV] on email subject and putting this ADV label for me, i found one new ADV email from my usual ADV email that coming from local bank, forum etc.

most of the time i might just flag this as a spam and throw it to my trash folder, but i decide to play nice and click on the unsubscribe link , the process go pefectly fine and guess what i getting ?

an unsubscribe email from QMax , eh how this QMax getting my email ? Oh the one doing wireless SG, ya i did give them my email when i try to sign up a wireless SG account, but are they allow to spam me that something not related to their service ?? Did i blindly agreed to receive this kind of spam when i sign up ? i fire up my browser and check on Qmax’s web site privacy policy. This is what i found.
