I have always had good service in the past but on this occasion the installation of a washing machine resulted in a chunk taken out of the wall in the entrance to the utility room where the installation had taken place. The house was otherwise empty at the time after a 4 year renovation of a listed property. The installers claimed that the damage was already there but further investigation revealed that this wasn't the case plus the pieces of the wall were freshly deposited on the floor. Accidents happen and the washing machine is heavy. The annoying thing is the denial that they caused it, let alone the lack of any apology or compensation.
