Xiaomi Redmi — mobile charger damaged

Address:	190023
Website:	www.mi.com

I recently bought mobile phone from mi store. The charger was working fine for 2 days then it stopped working. I called the customer care at first they told me we will replace your charger. After couple of weeks they told me we can't replace only charger we have to replace whole mobile, but if you visit service centre which is 300 km far away from srinagar then we can replace your charger even though this statement is not written anywhere in replacement policy. Hope you can help me regarding this issue. Thanks
