Bad Bad Service - False information regarding the repair of my Microwave!

On the 16 March 2018 I punchers an 42L NeoChef Black Smog Microwave Oven with Smart Inverter for R2800. On the 1st September will warming milk in a glass cup the glass touch screen door started to shatter? I immediately switched it off and took it to PICK N PAY Hyper in Faerie Glen. I went to customer service and repairs and the lady that assist me call a man the work in that department. He didnt give me his name however he told me that it needs to be send back for repairs and will have to wait 2 weeks. Last week Thursday i called the store to find out the progress of my Microwave and spoke to a man called Jerry. Jerry was telling me that it cant be fixed cause the door does not cover the 10 year warranty? And that I put metal in the microwave? how can he accuses me like that!! I know what a microwave look like that exploded cause of metal....... I told him that he needs to proof his accusation cause will take him to court i know my consumers law.... What the hell? I then asked him why did the person told me they gone send it for repairs? if he work in the department he should know the products rules? Jerry was not very nice and understanding and just told me that there is nothing they can do and the person that took the microwave from me will call me with feedback from the supplier? I am still waiting on that call. I took it upon my self to google LG service center and spoke to Micheal how told me that they only received the microwave last week Wednesday the 12th Sep. Mind you i took it on the 1st Sep to the shop. She told me they are waiting on parts and it will take 10 days for the part to arrive.... she was very helpful unlike Jerry how almost gave me an heart attack for talking pure **** with me! The worst customer service every! I will call her again to follow up myself because clearly Pick n Pay employees dont know nothing and giving false information. I paid too much for an microwave that i on used for almost 6 months. Jerry should find a job that he have knowledge of before he just say things to customers. Companies get bad names because of people like Jerry!
