Call and never leave message blocked and delete

Called on mobile and didn't leave a message. No idea who they are.

heard my message and hung up, seem to have a lot of numbers in those sequence's, used for annoying ppl

Caller: unknown

Called me at the usual time for anonymous calls - late afternoon. I didn't answer, checked the number here and found lots of other people who had received calls from it. Blocked it.

No message left can’t be serious.

This number called me, I didn't answer because I didn't recognise the number. No message left. This number is related to 80+ other numbers from the same people, always the same response when you call back. From all different states, and sometimes mobile numbers. Always the same switchboard. I have blocked nearly 90 numbers, I believe they are debt collectors but I owe nothing to anyone so it must be a scam.
