spammers

Since 26-09-16, I have received many spam calls, and when I asked Google AI, it said these are computer-generated numbers. The numbers are not phone numbers but look like landline numbers. Many people have commented on them as loan scams, fraud calls, voice scams of this type. So I wanted to find out how long these calls will continue and when they will stop. Please tell me if anyone has any idea. Usually, only 2-4 such calls come in a whole day, but sometimes the numbers appear as Axis Bank, Jio Care, or similar.
