LG Electronics — Product Out of warranty due to Lockdown (COVID-19)

Dear Sir/Madam,
I am a buyer of your Air Conditioner (AC); Model number: LG AC KSQ18AWZD (5 STAR-INVERTER) 1.5T SPL.
I bought this product on[protected] with a one-year warranty. But in this season its service is due. For the past months, I have been trying to connect with customer care. But your official customer care number: [protected]
was either temporarily unavailable or closed ( I have call records). After multiple trials on the telephone number which I have mentioned above, I have finally got the chance to file service requirest through "Whatsapp" on[protected]. My request number: RNP[protected].
On the next day[protected] your technician came and said that your product is out warranty (ONLY 4 DAYS AGO) and now you have to pay service charges.
I request you to kindly understand my situation and extent my product warranty time period as I have been trying to connect you from last month.
Being a customer of LG Electronics for so many years, I am not expecting this type of betrayal from your side.
Thanks & Regards
