Beware Online Buying Appliances Needing Installation

I purchased a ceiling fan with a light from Leroy Merlin Online on 7 March 2023, including R900 for installation. The installers duly came, assembled the fan and tried to install it. They were unable to find a wooden beam to install it securely, so left, saying that my installation fee would be refunded. It arrived several days later. As soon as the original installers left I arranged for my own electrician do do the installation the next day. He did it properly and securely. On Friday 15 November the light failed, though the fan still operated perfectly. On Monday 18th I sent an email detailing my purchase, installation history, and problem. Despite interim chasing I only received contact from their couriers on the 22nd asking me to confirm my address for my "collection". I pointed out that the fan still had to be uninstalled, and a new one assembled and installed and I expected Leroy Merlin to cover these costs caused by their faulty product. Despite chasing several times, I today received a message that a "follow-up" is being done. Nearly two weeks later I still have no idea when anything will happen.
