Symphony — Control panel not working

I have purchased a cooler diet 3D 55i+ tower and since second day o[censored]se it's not working and after raising tickets many time technician advises us to use it the way it is. And goes away.

One of the worst product and worst service provider.. buying symphony products means waste of money after raising many complaints a useless technician comes and advices us to use the defective product. And top of it he closes the ticket with informing. After sending emails and raising many tickets it's still not resolved. A advice to the company if you can't maintain your product or services please shut down your useless company.. and please don't buy any symphony products
