One of their marketing person calls to people at their desk line for marketing purpose and tells to receptionist to ask management people to make a callback ASAP. They even do not bother to tell what purpose need to be made callback. When we call them, surprisingly they will start selling their product. I feel really this is dirty marketing and waste other people's time and money.

This kind of marketing will not help but just create bad impression for company. Please advise your callers [marketing team] to avoid such bad tricks.
