It's no different from the telemarketing calls I take at work where the person calling seems to have access to company information (owners name, etc) and is offering whatever product or service. For one thing, you can barely understand what they are calling about because their english is not very clear and they refuse to leave a name and number where
they can be reached at the owner's convenience. They always say "no, we'll call back at a better time" or "no, there isn't a number where you can reach me", like their phones only work in one direction... yeah, right.
If they cannot provide their information I tell them we don't do business with anyone we can't call back so bye-bye and remove us from your list. These responses tell me that I'm not even dealing a person at the ABC company who wants our business, just someone working at an "outsource" location.
