We are sorry to hear that you feel the service you have received has not met with your expectations. We were upfront about the timescales in which we could deliver the work and met with every agreed deadline. We also squeezed in an extra day of emergency hot water repair work within just a few days of the issue becoming apparent. Additionally, we had one of our office staff travel nearly 2 hours to drop electric heaters to you at no charge prior to any work being undertaken. The system was tested in your presence and left working correctly upon completion. It is unfortunate that some of your existing valves are now failing but the issues you are experiencing are completely unrelated to the work we carried out. We have gone above and beyond in trying to assist you, even taking a call before 8am on a Sunday to talk you through dealing with a leak that had been caused by yourselves. I am sorry to hear that we cannot add you to our list of 1000's of satisfied customers but feel we could not have done any more than we have already done to ensure your satisfaction.
