joff_nz: Hah, no. Regardless of policy, (whether it officially exists or not), is it reflected in the terms and conditions or agreement the customer had/has with telecom?
Really, reflects under common sense for the customer. Sometimes customers find their way around things (getting interest free payments from Telecom because they have broadband, using the phone on another network for example). Telecom is not really a finance company and the interest free payments are part of postpaid plans.
They're a business, not a charity case.
