So i deposit the phone with xiaomi service center, agra on 19.08.2016 bearing jobsheet no. Js[protected] at the time of receiving they told that i will get it repaired within 7days. But unfortunately i am not get it. They told that the parts are not available.
On 31.08.2016 i went to xiaomi service center and meet with the manager mr. Dayal (Mob. No. [protected]) & service engg. Pawan kumar they told me that repairing may take 45 to 60 days.
I also want to know if company is not having any stock for parts why they are selling this mobile, meanwhile what customer do without phone and if company is not planned for it.
