I am deeply frustrated with the lack of communication you've demonstrated during this service call. Last evening, at approximately 5:40pm I was advised that your technician would not be able to get to my home to perform service. I further advised that a technician would be available between 9am and 11am today. It wasn't until I reached out to you via phone that I was told that you did not have a technician available who could meet the timeline YOU specified. I would have appreciated any sort of communication providing me with this information so that I did not sit around the better part of my morning waiting on a technician that you knew would not arrive. I expect that you will make every effort to communicate delays and issue you may have in servicing customers, so that they are not held hostage by your inability to be transparent. It is now 11am EST. The person with whom I spoke at about 10:48am today advised that your technician was running approximately two hours behind schedule. I expect that you will communicate any further delays or disruptions so that I may adjust accordingly.
