I received the same thing today; I been receiving alot of calls from fake numbers lately. I recommend that no one press any button when you are asked to approve or decline the loan. For all I know the hacker could register the button as approved instead of declined.
Robo Call for a loan scam. Do not respond to it in any way, including adding yourself to their "do-not-call list". Doing so tells this illegal caller that your number is a working number, and they will know to add you to other scam call lists. You can block the number if your phone allows you, but it won't help much. these criminals work from hundreds of other numbers, and they can create even more fake numbers. Just suck it up and don't do anything to make the situation worse.
