How to P*** Off Customers

We recently received this letter:

“We are currently reviewing the credit lines of our account holders to ensure that the appropriate line of credit has been established. Recently, we’ve noticed that you haven’t been using your full line of credit. As a result, we are decreasing your current credit line with Office Depot. Hopefully, this will free up your credit for other business needs and reduce your company’s exposure to fraud. There’s no need to contact us – the credit limit on your account will automatically be adjusted to the amount listed above.”

Is it just us or is this a dumb way to do business?
