They've called my cell phone twice and did not leave a message either time. I called back and got an automated system, which did not give any information about yhr company, not even their name. I did get an opt-out option, so we will see how that goes.
I got a call from this number and 417-800-2707 in the same hour this morning. Called them both back after they left no messages and had the same automated voice asking to press 1 to speak with someone, and 2 to go o the no call, I pressed no call.
When you call, it says it's a "customer service management platform" and you can select to have your number added to the do not call list.
If you try to transfer to a customer service representative, it just asks you to leave a message.
