I too got a call from this #. Turns out if you call it from a different line from the one they called you on (like I did). A computer says you've called WCA Subscriber Promotions and it doesn't recgonize the number & if you want to be removed from the subscribers list to press 1 and input the number you want removed. So I did and all it said was thank you & to wait 7 days for it to be fully removed from the database.
