This customer has been spending this amount for years and perhaps something as subtle as reminding him how close he is to receiving his rewards would be enough to encourage him to spend the difference. With this tiered service, the level of commitment to a customer who spends below the allotted amount on rewards and incentives, should have no influence on the customer service provided by OTTP. The tiered system, if set up correctly, can be an effective tool for both the company and customers. All customers will receive a high level of customer service, but those who spend over 100,000 will receive extra special service. There's nothing wrong with that
