Four stars is for the professional manner in which our complaint was handled by Daniel, the manager. Our initial experience with Mr Sparky wasn't that productive. We were not 100% satisfied with the service we received, but paid the technician the "flat" fee that he charged us, even though they didn't complete the work requested. It was the end of a business day so, we figured we would just speak with the manager the next business day. (The following Monday.) We left a message with the manager on Friday, late afternoon. The manager, Daniel, called us first thing Monday morning and rectified the situation promptly and professionally. We were very happy with Daniel and how he handled the situation. I will say that if we use Mr. Sparky in the future, that I will feel more comfortable doing so, knowing they will stand behind their word and their guarantee.
