Called back, recorded message says "Teleperformance, contacted you on behalf of Dow Jones" (e.g. Wall Street Journal). They do not have my permission, so I am filing an FTC and FCC complaint.
Called several employees on their direct numbers, then the company main phone line. No one on the other end when answered, they just hang up. Spam, telemarketer, or prank.
Wall Street Journal trying to get a former employee to renew their subscription. Repeated attempts to be added to the do not call list have failed. Will try the suggestion about asking to be put on the call center's do not call list and see if that works any better.
Teleperformance calls my business phone at least five times per week and as much as 3-4 times per day asking for someone I have never heard of. I now just transfer them to "Tom" and see how long they wait on hold.
Even though I have asked to be removed from their list, they kept calling. So now I feel good about maximizing the negative impact calling my number has on their profits/loot.
