Faulty Microwave which didn't even work for 3 months after purchase!

Purchased an LG microwave (Repair ***, LG Neochef 42L Mwave MS4235GIS)from GAME Stores Wonderpark mall (Pretoria North) during February 2018. The microwave started giving us problems in May 2018 (3 months after purchase) and was taken back for repair. It is however unfortunate the microwave has started giving us problems ONCE again even after the attempt by the store to fix it. I am very disappointed and can at this stage only accept a full refund or replacement (brand new microwave).
