Always been very satisfied with the service. Until now. My son bought a washing machine there and had it connected. After 2.3 washes, the water sprays from the tap / hose connection. The employee has come by, the connection has been tightened further (in my opinion not properly connected, photos as proof), the spraying of the water stops immediately. The reaction is that that is not possible, that it should have leaked immediately. You let it plug in, so don't assume leaks, drips. Recover any damage from your own home contents insurance.
