Rule of thumb I've heard is that for every nine dollars it takes to attract a new customer it takes one dollar to retain an existing one - the lesson being to value the customers you have. I'm not sure if that's 100% true and I'm sure it varies by industry, location, etc. somewhat but even if it's 1/4 true, it's a pretty stupid business model to think you can strong-arm your existing customers into being "upsold to". Sounds like a Midwestern / Chicago company / tactic.
