I think paytm guys are defaulters. I have ordered a laptop fujitsu a 514 lifebook. on their website they are showing its battery backup is 8 hrs. so I have ordered it. after using it for some time laptop keeps on hang and battery is giving only 3 hr backup. so I contacted paytm support for that but they didn`t answer my queries.
they do not have phone support.you can write mail to them but I didn`t get any satisfactory answer from their side.
