Plumber didn't call me prior to visit to let me know when he would arrive, he called me once he had arrived! Needed the ball cock replacing and the guy replaced the faulty part but literally ten minutes after completing the work and leaving my premises i tried to flush the toilet and it still didn't work!!! I poked and prodded the inside of the cistern and fortunately somehow it started to work!
I'm not very satisfied with the overall professionalism of the company due to no phone call to say he was on the way and then i had to readjust the part that he had just changed? Wouldn't use this company again.
