Called this morning around 810am. Said hello and no answer. I don't ask hello twice because that's usually their trigger that someone is there. I always wait to hear fake busy tones, or for someone to come on again to know if it's spam or not. Two different busy tones came on while it still held the call, so it's spam. I held the call for 5 minutes.
Also when you call then back, it's a recorded message in a female voice talking about their office hours and if you press 1 for more information, they ask you for your phone number with area code.
