Received several calls from 210-853-2837 and when I answered nothing but after the second time when I tried to hang up it was a fast call back. I was finally able to call and sounded like they said it was WCA Subscriber Service . It said that number was just for subscribers and it didn’t recognize my number if that number should be removed enter number, said it should take 7 business days to remove number from service. Will see if they continue to call.
