Have gotten two voicemails today, no one speaks but can hear multiple people talking in the background like it's a call center/telemarketer

They call you and tell you that you have won a gift and ask when is a good time to deliver it. They ask for your age range and income range. Then you get a call from a sales rep to confirm the time for him to come by and give you your 'gift' and to talk about retirement and tax savings in a 20min presentation.
