Disappointing experience.
I uncovered a problem with the wall built as part of this job - I contacted them several times and heard nothing back.
I mentioned several times during the job it was absolutely key that the wall they were tasked to build wasn't too high - the height had to be precise. The wall is fine at one side and too high in the middle, by a mater of 2-3cm. This doesn't constitute precision to me.
I understand that mistakes happen, and even if their team had come back and offered to adjust the height, or cut the top of the bricks slightly i'd have been happy. To not respond to my request for help is very poor form. I'm now in a position where i'm going to have to do this work myself, having already paid them.
It saddens me to have to leave negative feedback - their team were very friendly and more than helpful during the work, which is why I'm so surprised they haven't offered to help sort out the height of the wall. Unfortunately negative feedback is the only option I have.
