for those Chinese telemarketers. They simply do not care, keep calling everyday.

I tried to pretend to be tenant, English only, or throw Japanese or Swahili (basic greetings). Nothing works, it seems they are from different groups representing different companies.

When it is regular English callers (non-Chinese), they disappear once they were told you are on no call list and do not want to be disturbed. But for Chinese, it seems they have a list on hand, unless the list is cleared for business, they keep calling.

If you were bothered by this, how did you stop it?
