Your number was somehow high jacked/sold, and being passed around to multiple scam centers likely in Jakarta or the Philippines. Spam waves will fluctuate, but they usually die off. The most important thing you don’t do, is answer any of them, because they have an algorithm that actually can determine if you answer these calls, and said calls continue to persist.

If I were you on a cautionary note, I would keep watch on your credit monitoring/credit score and bank account(s). If you have alerts that can be enabled for any activity on your account, I would make sure those are prompted.
Never answer an unknown call. If it’s important, a voice mail will be left. Afterwards , no voice mail? Consider blocking the number.
