Poor after-sales service

I am extremely dissatisfied with the after-sales service I have received from LG. In December 2025, we purchased a refrigerator from LG Electronics, which cost over R30,000. Within days, the water filter developed a fault. I immediately contacted LG. I was assured that a technician would be dispatched within three days. No technician arrived. When I followed up, I was informed that no service request had been logged. This was unacceptable. A new service request was then created. I was again promised that a technician would make contact and attend within two to three working days. Six working days later, nothing has happened. I have received no updates and no indication of when the issue will be resolved. This experience has been deeply frustrating. I have an expensive appliance that cannot be used to its full functionality due to poor after-sales support. Is this the level of service LG provides after a sale is completed?
