Leroy Merlin, Ariston and everstream Poor Service

I bought 6 Ariston 30L Portable Geysers at Leroy Merlin Greenstone ( Stoneridge Centre) on Sunday 22nd Feb 2026 an my plumber installed them on Saturday the 28th of Feb. After installing them we found out that 4 of the geysers were working as expected and the other 2 were not switching ON. We uninstalled the 2 that were not functioning properly and i took them back to the shop the following day which is Sunday the 1st of March 2026. I go straight to return whereby i was told that geysers are not supposed to be returned to the store if they are not working. As frustrated as i was since those geysers were supposed to be used by tenants i decided to leave them there and the following day Leroy decided to courier the faulty geyser back to us to install them. We did as they advised and installed them. They said they will send out technician (everstream) to come and have a look at them. The guy called Sihle Zungu who seems to be the owner of https://www.everstream.co.za called and promised to send out plumber the following day with no luck. The plumbing department manager (Cliff Makhubele) from Leroy by the name of kept on promising that he will call me back but he never bothered. I had to find numbers for Ariston sales manager (Lucelle) but she kept on telling me that the engineers will go and fix it. When i called both Ariston Luccelle and Leroy they keep on referring me to Mr Sihle Zungu who seems to just play delay tactics. I am so ****ed off by these 3 companies hide and seek game. All i want is for them to refund me or fix their geyser. Bad service
