Lloyd — Lloyd split inverter AC compressor not running ac not cooling

I've registered my complaint three times to consumer care of Havells for Lloyd split inverter AC not cooling and it's compressor not running all in the time span of 17 days starting from 10th April, 2022 to 27th April, 2022 and all the three times the workshop where the Havells company have assigned my request cancels it without resolving my issue and without contacting and informing me, not only they've failed to resolve the issues with the ac but also are cancelling the registered complaint with the company and in addition has the worst service ever. After a tiresome efforts on my part I was able to get the manager's no. Of the workshop whom I called and enquired about the same, who told me that the part of compressor which has issue is not available in our workshop nor is available with the company, a Part Po(Purchase Order) has been created and will be delivered on Wednesday, 28th April 2022 and that on the same day will be sent to my house along with technicians to resolve the issues but still has not been done by the company. My ac is still in the guarantee period and was purchased a year ago but the attitude of company and workshop and of the Manager is questionable as if they're waiting for my ac guarantee period to get over so that they can charge me with hefty amounts of money in the disguise of part not available to them.
