Bad customer service

My geyser broke and King price sent someone to fix it. After a month or so the geyser didnt warm up so we called again and asked if someone can please have a look at it. Keon came and said the geyser is working and the trip swich was the problem. They also saw that the geyser wasn’t directly over the drip tray, why much I pay for something that was done half way? When I spoke to a manager this week she said it we wanted it up to standard we must pay for this, why should I pay for something that was suppose to be done correctly in the first place cause she doesn’t want to send someone out for no reason. I have children in my house and what if the geyser bursts again and the warm water falls on my 4month old. This is unacceptable from their side. If they dont care about their clients they shouldn’t be selling insurance!!!!!
