They call my landline all the time! I just found out who it is! Sort of...I called it back with a blocked number and a recording said, "Welcome to WCA subscriber services..." and then said they don't accept calls from a blocked number! and to call back on another line or unblock my number. Ha, not gonna do that.
So then I looked up WCA Subscriber Services and there are a few but I think it's this one, although it could be a different one:
"WCA operates the Special Offer Service, a unique subscription-based program that rewards consumers for consenting to receive recorded messages that include special product offers and purchase incentives. Subscribing consumers are automatically entered into a daily cash sweepstakes whenever they answer one of our calls and thousands of dollars have already been awarded. For more information about the SOS, please visit: www.specialofferservice.com
The SOS program was created in order to comply with state and federal regulations that govern the transmission of automated voice messages, and WCA is committed to making it a positive experience for all subscribers.
This website is intended as a resource for subscribers and non-subscribers alike to learn more about WCA and its policies, and the steps they can take to protect themselves from unscrupulous telemarketers, and to secure their privacy online."
