Dell India — problem regarding technical support

Address:	Ahmedabad, Gujarat
Website:	Dell technical support

I am using dell inspiron 5558 and i am facing port issue in software installation. I have tried to get solution from technical support but they did not give proper solution and even didn't answer properly. I got angry because of their behavior. They were answering silly things. They said that our department was not working and can not register complaints and so on. This is not fair because i leave my work that day because of getting solution but i can not achieve it.
It was very bad experience from dell support.
