Based on this confirmation, I bought laptop. Laptop i received has manufacturing issues. Monitor was always swinging when placed under fan. We did not realized it was manufacturing issue. About two months the hinge connecting monitor to rest body got tore away. When I contacted Support folks with respect to warranty and explained issue. Support person has indicated that part will be replaced. Technician home visit is not covered under warranty. So I need to take it to nearest service centre. Before taking service centre, Support person also communicated that i need get warranty transferred to India. Support person took request for transferring the warranty. After receiving mail from Dell, I took my laptop Service centre. Based on the conversation, I had what i understood. Since laptop was bought in US, Warranty is not supported in India. If parts have be replaced under warranty, I have taken it to Service centre location in CTS, California. Otherwise I have bear cost of repairs. When I referred by conversations, Person in service centre has communicate that today being Saturday the support help desk will not be working. Pl. go back and call help desk on Monday and get me reference number for the conversation. Subsequently I called Dell help desk. That was most painful conversation. First person does not listen to understand what my problem was. He kept on interrupting and rambling to point of being rude. Several times just retorting why does I need reference or case number for the conversation. When I have pointed he is being rude and then asked him why Service centre person asking case / reference number for taking up warranty claim – Then related. What he communicated is that I should ask service engineer visit, who would visit home and replace parts under warranty. Based that conversation I have paid for visit. Then day before yesterday I had received call for service engineer. He asked me to explain the problem. When I did, he has indicated that I need pay for all parts that needs to be replaced. He indicated that he will send quotation for which I need to pay. When I referred to my earlier conversation, he said that he needs to have conversation with teams and get back to me. Now my question –

Who correct person to escalate this issue and get it this issue resolved. It has been approx. a month since issues is going on.
