Lalela Inverter - definitely a NO from us

We bought 2 Lalela Trolley inverters at Leroy Merlin in December 2022. The one started beeping last night and it wouldn’t switch off unless it was plugged out. It showed a Error Code 7 - which according to the manual means it’s a fan issue. We took it back to Merlin Leroy today, 12th August, to be told that it needs to go back and repairs will take 3 weeks. It’s a huge issue as it is needed for business purposes and after a discussion with Anthony and Lodwaba ( they phoned Lalela Retail) we were told that a technician will go to Leroy and fixed it on site today. However, after 30 minutes ( shopping) we were told it will now take 3 days. Firstly I have a huge problem with Lalela and Leroy Merlin as we believe, and according to the CPI regulations, the unit should have been replaced not repaired. Secondly, once we get the unit back the original warranty of 12 months will stay unchanged. Nothing about this arrangement is fair. As far as I am aware the unit had to be replaced with a new one and that should have been done by Leroy Merlin. The damaged unit should then be returned to Lalela Retail. This practice is in line with all arrangements between a retailer and a manufacturer. This is a “proudly “ South African product.
