Dear Mr Stannah,
Thank you for your letter of 23rd . Just addressed to my wife. We have already completed and returned the questionnaire following the instillation of our stair lift on 22nd of July.
It is heartwarming to discover your service has been impeccable. Peter Greenhalgh, your sales consultant, visited within hours of my wife’s phone call and the subsequent visit to install and demonstrate the lift was superb.
Congratulations and sincere thanks- this is an object lesson in how to handle customers.
