Samsung — Air conditioner Unfinished Installation, Informed to Head office, no action taken

Uncompleted installation, I don't know why your Technicians are this much lazy and not having any work ethics. My details have been shared on Samsung Facebook page inbox, I have given complaint twice, still they have given unfinished/ half finished installation. My Ac installation hasn't been completed fully, I have asked them while doing the Installation, but they said it is ok, but my machine will be damaged if it is left like that in open air. Rain may corrode the pipes
