Symphony Limited — Symphony wall mounted air cooler

Hi, I have purchased Wall-mounted air cooler from Symphony on 18/02/2022 and received the product within 10 days. Installation done on the next day of the arrival which was good. Now, the actual issues started one after one.
1. Water Leakage issue (Technician said the it happens when the water level is heavy and happens once in a blue moon. Actually, it is happening once in every 2 days)
2. Fan started running slow sometimes (I was told by the technician that the issue is with the PCB. He said that he will inform the management to replace it. It's been more than a week but this issue is not resolved till the date)

I called customer service team and that was a nightmare. I was told by the agent that there is no manager/supervisor available in the Company. I don't know which company runs a business without any Manager/Supervisor.

I have few of my friends who cannot buy an Air Conditioner. I thought I could refer this to them so that they can save Money and get what the want. But, unfortunately I feel bad buying this product as it is no use.

I would appreciate if someone looks into this matter and help me to get proper response or refund my money.

Thanks in advance.
