hutton east plumbing

Hutton East plumbers appointed by Fogi. Tried phoning cell & landline number of plumber but no answer. Message received from Fogi - " If plumber has not contacted you then please contact them" So I tried both numbers again but was still unsuccessful in contacting plumber. I am unsure why it was my problem to contact the plumber. Forwarded message from Fogi to plumber and then suddenly received a callback immediately from the company stating that they are so busy and can only support on Friday morning at 8AM and promise to resolve everything. Why did they take more business if they are so busy? I advised that I have a heat pump connected to geyser etc. and advised to send someone familiar with setup Came out and could not assit with heat pump
