Trust me. My brother is an electrician. He is not around and that's why I had to ask these guys.
All I did was just politely ask them to show me the old component. They had changed the components twice and they never shown me any proof. We just had to believe them as if they are some close relations of us.!!!!!? He talked to so indecently that I had to just give him the money he asked..
NO RESPECT TO CUSTOMERS...U would not want to call National Electronics again.They serviced us twice. Not good..!!
