Aggressive and Unsolicited Telemarketing - TS Consumer Insights

I'm writing to warn others about TS Consumer Insights' aggressive and unsolicited telemarketing. Today, I received an unwanted survey call from them on ***, despite never providing my contact information and being registered with DMASA (dmasa.org).

The representative refused to disclose where they got my number, talked over me when I said I wasn't interested, insisted my participation was required, and refused to remove my number from their database. I was forced to hang up.

This experience was extremely unprofessional and disrespectful. I strongly advise against engaging with TS Consumer Insights if you value your time and privacy. Their disregard for the Do Not Call Registry is unacceptable.
