I bought a new battery for my xps 15 l520x laptop through an dell exclusive store located in erode (Tin-[protected] gstin-33avbps9190f1zd). It turns off when the battery level fall below 60%. I have to charge it after that and use it till it reaches the 60% and the story continues. I went to the store and informed them about the issue. They told me to downgrade to windows 7 (Which i did) but the problem never got solved. They told me they will sent it for replacement. After 10 days they called me and told me that the battery was fine and the problem might lie in my laptop. I approached the store where they told me that i have to pay rs. 300 for checking my laptop. I told them it was not necessary and i would like to get a refund for the battery. They told me that refund is not allowed. Now i am stuck with a faulty battery for rs.4900. The only option available to me is giving the laptop for repair to them (I don't trust them as they don't use a dell service unit and they are using a nearby multi-brand shop). I bought the battery on 12-july-2018
