This is a scam call. Since downloading a job search app on my phone, I have continuously received scam calls regarding at home jobs, online school, etc. These are all fake so please don't believe what they are saying. These Indian sounding folks use scramblers to appear as though they are a phone number in the USA (most likely with the same area code as you are from or have frequented). When trying to call the numbers back, the phone call cannot be completed. Honestly people if you're getting these calls, have your cell number changed! The do not call list can't and won't help you in these situations.
