Electrolux geyser warrantees - not worth the paper it is written on

The thermostat of our geyser failed. Electrolux refused to replace it, however it was still under warrantee. Their technician who was assigned to the callout claimed that it was caused by a loose connecting wire when it was installed (Feb 2024). If this was in fact the case, the problem would have surfaced earlier. Our plumber who installed the thermostat came out to inspect, and very clearly demonstrated to us that the alleged loose wires were all in tack. The problem was definitely not caused by a loose wire, but rather due to an internal manufacturing or quality defect. We have a video to prove this. I also have to mention that the 'inspection by the Electrolux technician' literally took less than 10 minutes. Electrolux will use any excuse not to honor their customer service commitment. I will never use this company again, and I'll definitely not recommend their services to anyone. Our plumber also stated that this is a recurring issue with Electrolux warrantee claims. A 1-star rating is too high, if I could rate them any lower, I would.
