Title Customer's Billing Query
Organisation EDF Energy
The company, EDF, is one of the largest energy suppliers in Europe with 5M customers. When dealing with an everyday enquiry about billing, operator Carol has to reassure a customer that the bill is indeed correct. Carol has a formula for working out the bill, and after finding the number of days charged – and knowing the higher rate is for the first 2.45 units, with the remainder charged at the lower rate – she can reassure the customer all is well. During the call she uses a formula, decimals, proportion and a calculator.
