Service appalling

Service appalling Fixed aircon pipe that was leaking, Told me they don`t plaster (Which I accepted) and technician took it upon himself to Plaster anyway which was done so badly, I mean really bad and now they just refuse to come fix Just costing me more time and money Shocking service Will never use them again and will warn others accordingly to very poor workmanship I wish I could upload the Photos so you can see, When I say bad plaster, It Took me hours to grind it down to be level again and still did not get it right, Have to live with it because if I grind further it will damage piping which again was not deep enough in wall and will end up having to be replaced again which is expensive Attitude of staff also appalling, Don`t even want to hear you out, So no more business from me
