Sargam Electronics — No cooling is there in Split AC and noise is coming

Address:

Sector 18 , Atta Market , Noida , UP

I have taken extended warranty of 01 + 04 years for 02 Split ACs,
Cooling problem and lots of noise is there, nobody is attending inspite of various calls n WhatsApp messages

Is there anybody senior over Service Head / Executive, who will listen and resolve

Really very very poor services, it seems nobody is answerable, nobody knows the meaning of CUSTOMER

Bhagwan bharose chal raha hai
