Caller: Trading company

Said I enrolled in their trading or investment company. When I said no, and not interested, he won't stop and keep talking... I didn't have time to waste, just hung up and blocked the number

Caller: Scam Center

Sounds like a call centre trying to sell online income. However, the individual became rude when I said I was not interested and wanted to be removed from their dialling lists (many similar numbers). Nonetheless, they persisted aggressively, not respecting what I had asked, so I reckon it's just a scam call centre
