Llyod Logic Systems Private Limited - AC service

This is in regard to complaint I have lodged * month ago. There was a request to reinstallation of AC unit in our new home and we requested for a service and a technician from llyod have visited and did it but in a wrong method and made whole AC refrigerant was leaked due to ill skilled labour. After a month we have switched it on as it was bit sunny day and found room was not cooling efficiently and so raised a complaint against it again and the same guy visited from llyod and told what we were expecting (leakage of refrigerant) and told he will come back and get it done. It’s almost more than a month we call customer service agents alternate day enquiring about the status of the complaint and they say we have allotted another technician and he will visit you today and that day hasn’t come till date.... kindly I request you take precautionary actions against this how come a well known brand services would be this worse. I want my AC to be served or replaced or get my amount refunded because it’s mere waist of money having a product of one of the worst services I have faced in India.
