10 YEAR WARRANTY ON MICROWAVE CAVITY NOT HONOURED.

I purchased a LG microwave in August 2017, with serial number MS5643GARS 56 L, from the House and Home in Arbour Crossing KZN. It came packaged in a sealed box with the relevant documents, including a sticker across the glass of the microwave indicating 10 YEAR WARRANTY ON CAVITY ONLY. In July 2021 I took the microwave to House and Home in Arbour crossing, as I had found rust build up on the cavity. I was assisted by Cindie Shangease who called me a few days later, as LG required pictures of the rust on the cavity. I emailed pictures to her and thereafter received no communication. Due to unforseen circumstances I could not pursue the matter further, until November 2022. I was requested to take the microwave in to IRS, the LG agents in Pinetown KZN, this I did on 22 November 2022. I was charged an assessment fee of R200 and it was brought to my attention that the 10 year warranty would be a problem, as no one had heard of such warranty before, on 23 November Moses from IRS informed me that LG was unable to repair the rust and was offering me a chargeable exchange, with documents to be Forwarded to me from head office. There was no communication thereafter from Head office or IRS until I, after numerous unsuccessful calls to IRS, called LG head office personally. On 7 December 2022 I was assisted by "Shaun" who informed me that IRS was still awaiting instructions from "Shantel". On 9 December 2022 I got a call from Dangi at head office informing me that I waz being offered a chargeable exchange. Documents were emailed to me and as per these documents I was required to acknowledge and sign that because my microwave was out of warranty I was being offered a chargeable exchange. I was requested to pay R 2598 to get an exchanged microwave. I refused to sign and examined to her that my microwave was still fully within the warranty period. I was then told that the problem arouse with the serial number and the date if purchase of the microwave (2017). The date of manufacture was 2016. I was asked to provide proof of payment, which I did. After numerous calls to her I was later told by Dangi that the Magnetron had a 10 year warranty, not the cavity. I sent pictures to her via email showing that the 10 year warranty was on the cavity. She requested that I email her a letter of complaint which she would forward to management that would be investigated (21 December 2022). I received an email stating that nothing could be done by management, that I had to pay the total amount for the exchange microwave as LG works on a 30% discount. I am disgusted with the service from LG, a world renowned company, I received contradicting reasons as to why my microwave warranty could not be honoured. I paid R200 for a useless assessment and my integrity was questioned when I was asked to produce my cash sale. I don't ever want to deal with LG electronics again, as I believe that I was unjustly treated by this company.
