Sounds like a moderate sized operation. The phone picks up with an automated greeter and then transfers you to the next available agent where you go on hold for a bit. Sometimes forever, resulting in ‘not available at the moment’ hang ups, some eventually get picked up by a person. I haven’t got very far with them yet - just harassing them every chance they give. Only name I’ve gleaned so far is Jason Brown.
