Locked Out Heathrow

I wish to thank two of your staff for the very professional manner in which they dealt with the emergency call-out to my property. Firstly the lady who took my initial telephone call, whose name I believe was Kerry. She listened carefully to my problem and then proceeded to offer a solution giving detailed information on how to solve it. She was polite, courteous and extremely knowledgeable.
Secondly to the engineer, Tim Friedenheim, who arrived at the agreed time and immediately got on with the job. He to was extremely polite, courteous and fully understood what needed to be done to resolve the problem.
I have been involved with the training of customer service to both domestic and international companies within the United Kingdom and the USA and it always stands out when excellence is achieved in this field.
