called back this number, automated recording stated that one of their agents tried to contact me to take a survey. if I want to be removed from their list to press 1.
Just got another call from this number, as I did yesterday, and everyday for quite a while now.
The only thing that has changed is now the caller ID shows "DISCOUNT CENTER" instead of unknown name.
It's still the same telemarketer. I would never use any services offered through a cold call.
