I bought a Vostro 3546 laptop on 27 march 2015. I faced a problem around august as it was getting off when moved even a little and on charging sometimes says battery not detected . As i was near a servive center those days i got it repaired and they said it was due to hardware displacement problem. Now for past two months i am facing the same problem. I have called Dell customer care and they told me my laptop is out of warranty as it online says was warranty got over in august 2015 but as per bill its not, So they told me to send a copy of bill to a mail for update of warranty. I did that but even then they didnt updated and told me i need to send a scanned copy as that was a clicked photo. I did that again and even now my warranty isn't updated. I have called Dell around 30 times and each time they transfer my call and i need to repeat the same thing around 40 50 times but they are still not supporting. On 27 march my warranty will get over and service center isn't near me to visit. Please take some against against Dell service and help me as my work is getting affected and i need it to be reapired as it is in on site warranty.
