Contacted this company to repair a back door and replace the lead on my leaking conservatory roof. Came to fix the door which was great but couldn't do the roof as it was raining, fair enough. Arranged a date for a few weeks later which was cancelled and still waiting to hear from them. Have called several times and left messages as no on picked up and again still waiting for my callback.
