How to handle this call
Hang up immediately
Say "I'm not interested" and hang up. You don't need to keep listening.
If they call your workplace
If calls reach your company's main line, report them to your general-affairs department and ask to have the number blocked.
If they're persistent
Saying, "I will report you for violating the Building Lots and Buildings Transaction Business Act," is effective. If it continues, you can report to the licensing authority at the Ministry of Land, Infrastructure, Transport and Tourism.
