Speak too fast to hear where they're calling from. Have called me three times in 24 hours, never leave a message. Called back out of curiosity and as soon as it patched into someone, you could hear it was a dodgy call centre type scam. Hung up immediately and blocked the number.

Caller: Scam

Called 3 times over the last 24 hours, no voicemail and stoped calling after 3 or 4 rings.

Someone from this number has been harassing me, they have called four times altogether, as in twice a day for two consecutive days. As they never leave a message, the number is blocked.
