We got a call the other day from a company that was selling a service we actually need. The nice woman - who had pleasant Asian accent - said her name was "Jan," and that their office was in NY.
Anticipating a need in 4Q, I agreed to a demo next week.
Not 10 minutes later I received a call from the same company, pitching the same solution. The caller, who this time was male, and who had a different Asian accent, said his name was "Jan," too.
I told him to cancel the appointment and take us off their list.
