Mmmm, fake reps.
They’re not real amazon reps, they just indian scammers.
Lol that call center is loud and someone picked up and then hung up so this number is active.
It says that the voicemail system is full. It is bonked!
I think they call it the Amazon carding method. Something like that, I saw a post that explained how it happens.
I think this link should help

Amazon scammer said his name is Robin Medusa. Huh? Masala Dosa, I asked. Nope, it is Medusa. Whatever.
