how to write a buffer

For each situation, write a buffer, opening for Refusal messages. Try to use different types of buffers (See Buffer Types on UMMoodle) for each situation. 1. A letter from a travel agent to a customer stating that the airline will not refund her money for the flight she missed but that her tickets are valid for one year. 2.A letter from an insurance company to a policyholder denying a claim for reimbursement for a special medical procedure that is not covered under the terms of the customer's policy 3. A letter from an electronics store stating that the customer will not be reimbursed for a malfunctioning cell phone still under warranty (the term of the warranty do not cover damages to phones that were accidentally placed in the freezer overnight)
