Very bad experience

These guys used to be good, but seem to have downhill. I contacted them about brown water coming out of my geyser. They sent a team out -- which was only on my premises for 5 minutes, and did not even look at the geyser. Instead they told me I needed to contact insurance (which I told them did not cover the geyser). They then made me sign on a phone, and left.

Two days later I received an invoice for a R530 "call out fee" which had not been mentioned at any point, neither in the initial phone call, or when the team was on site, or even when I was requested to sign.
