If it is Linknow Media who would use a business that only has a linkedin page that shows no company address information, has no BBB or bizapedia report? They do have a website linknow dot com and a facebook page though. Website does show an address 4700 Rue de la Savane Suite 210 Montreal, Qc H4P 1T7 and linkedin page says marketing and advertising.
Called today and the lady asked to speak to the owner of the company (no first or last name). I said that the Owner wasn't in and was hung up on. I called the number back and it made some weird noises before anyone answered. The lady who answered was nice but seemed miffed when I refused to give her my number so she could "take me off her list". I told her I was hung on by a sales person and I just wanted to know the name of the company so I could deal with them accordingly next time.
