Check this company before buying a house

Think twice about buying a house with this company Miascope Construction & NHRBRC. My house is still insured with them for one year. My geyser started giving me issue after a week of moving in the new house. My neighbours said that the geyser was leaking hot water even before I moved in. Every single month I call the developer manager Thamy and he gets the same person to come and fix the issue but 6 months later, it’s not fixed yet. I’ve asked the manager to find someone else to fix the geyser issue but he always sends the same person and the issue hasn’t been fixed. I called head office 0800200824 & 011 593 3281 and they never answer or no one is available. My worry is it’s leaking hot water. Imagine the damage to my proof this will have. I’m sick of these people and I wish I never bought a house with them. It’s a headache. I reported the geyser and it’s been a week but no one is coming to fix it. Can someone please help fix this geyser issue in this house and please send someone to fix it properly. admin@miascopeconstruction.co.za Kebone@miascopeconstruction.co.za thenhbrc@nhbrc.org.za
