UPSET THAT I HAVE TO GO INTO LG TO SORT MY MICROWAVE>

i am so disapointed for the first time with my LG microwave. i purchased it in 2023 from hirschs. i called hirschs today to explain that the microwave had stopped heating again, i was told that i have to take it into LG as LG will now charge them R650.00. this microwave has been giving me a problem since i bought it. When i bought it in 2023 it gave me a problem after a month or so and LG was kind enough to replace it. in 2024 it broke down again. i sent it back to hirschs who then sent it to LG and was told that the PC was gone. they fixed the microwave and did not replace as it was still under warranty. Now we in 2025 and again this microwave has packed in. i have always been using LG since 1988 and have been really happy with all my purchases untill now. SO CAN SOME PLEASE RESPONCE.
