Will never buy another LG appliance again!

On 21.3.2012, we bought an LG fridge with ice and water dispenser at Makro, at a "special" price of R9199,00. We previously had a leak in 2015 which was repaired by the approved and recommended agents for LG, IRS Tronics. The fridge again leaked and on 29.11.18, Viren from IRS Tronics came out to inspect (at a charge of R450,00). He advised that the pipe inside the door on the freezer side had broken, and that the whole door would have to be replaced. After a phone call to LG, he told us that the model was obsolete and they could not replace the door as there are no spares. He promised to see if he could do something but regrettably has not been seen or heard from since. How can this expensive fridge be obsolete after not even 6 years? The service from IRS Tronics is non-existent, and we are now left with a fridge that is not operating properly. LG needs to explain why they are unable to repair this. It is unacceptable that they are unable to repair an appliance that is less than 6 years old.
