Dell service centre GOA — Not addressing the issue with the mother board - under warranty and incompetent service engr

Address:

North Goa, Goa, 403401

I have recieved the laptop after 15days, problem still persists - many Files/folders got hidden up (issue starts the day motherborad replaced on 16th MAy'15) - screen fluctuation/flickering - Itune backup data lost Not able to undertsand the expertise where it lies - out side of cap or inside of mind Before my laptop's warranty expired, I have handed over the laptop so that mother board can be replaced thougt it has not been undertaken. After speaking to your colleague/team member, he said hidden files problem solved and as per his expertise - files copied form hidden files and created a new folder wherein the files pasted and issue resolved. However I as leyhman dont believe that this step/activity should come from service engineer. "C" drive data formatted without my knowledge and now I am facing issue with pivotal docs lost which was saved in ITUNES. - as per discussion with your colleague stating he has taken a backup of c- drive and what i found he has copied all desktop items and pasted in folder named as c-drive back up.. WHAT IS THIS??? I need my itunes backup data back. PLEASE.
