I just had the same message: "Hi this is Adam from Momentum, give me a call back when you have a chance at 732-204-7790" message today. I did not call back. I will try to block.
My phone didn't even ring so I have no idea where number came in from or how I could block it but I got the voicemail just now that said the same exact thing... "Hi this is Adam from Momentum, give me a call back when you have a chance at 732-204-7790"
