My fridge which is on a 5 year extended warranty stopped working two weeks ago (had it since 2018)

My fridge which is on a 5 year extended warranty stopped working two weeks ago (had it since 2018). I logged a call to Makro and a technician came a week later. He can't repair it as it requires modifications to the gas lines. Internal gas leak. I've called numerous times to find out the way forward and still no joy. No one is giving me any feedback. I am extremely angry with the level of service. I am now going into the third week without a fridge. Can someone please assist me with this. I have reference numbers etc. Tired of calling Makro and tired of using the absolutely useless makro WhatsApp messenger to log my complaint. I'll never buy from Makro again.
