I get a sales call (8 PM, at home) from a company that I already do business with. I tell them to put me on the do-not-call list.
They tell me that I may get more sales calls for up to 30 days. I mention that it’s against the do-not-call rules.
They say “It’s OK, the rules don’t apply because you’re already a customer.”
Not for long!
(How many customer relationships can a high-volume call center destroy in one evening? I know they have a spreadsheet that tracks sales closed. I bet there’s no spreadsheet for “revenue lost due to relationships burned.”)
