Privacy policies...my arse

Wow...it's been a while since my last post...oh well, on to the subject at hand:

Lately I have been receiving e-mail newsletters from this one company (whom shall remain anonymous) for the past month or two and I have no recollection of subscribing to them, which I'm pretty positive I did not considering this company is based in Hong Kong. I finally decided to unsubscribe because their e-mails were bypassed my spam filter. Not to mention, my name in the newsletters was kai wa wong...that's no where near correct! Anyway, contact contacted me with this message:

Dear Aaron,

Thank you for your e-mail. Please be informed we are not able to retrieve your record according to this e-mail address (aaron.kwong@gmail.com). Kindly provide your membership number or the e-mail address which you have provided to your (name removed) account

Thank you for your kind attention.

This is how I responded:

Hi (name removed),

Another party must have provided you my e-mail address without my permission so, unfortunately, I do not know my super e account membership details. If still possible, I would appreciate it if you could remove this e-mail address from your mailing list.

Thank you,
Aaron

Now we play the waiting game...and now I'm curious who they received my info from.
