Worse service EVER!!!!

WayWes Plumbing is the worst plumbing company i have ever dealt with. They came to look at our geyser that was tripping last week Thursday, 20th and made an appointment to come this morning at 8h30 to replace the Element and Thermostat. They were a no show!! I had to phone 3 times and finally got a phone call back at 13h18 to say they will come at 17h30, however we have loadshedding at 18h00. Told them that wont work as it takes at least 3-4 hours to replace a 250L geyser thermostat and element. Waywes recons they can do it in 15-20 minutes! What a laugh!!
