Oppo — battery fault of new oppo f7

Address:

193302

I have brought one new phone oppo f7 before one month from local dealer, that oppo f 7 battery is faulty because his battery back up is very low, i m charging that phone twice in a day, when i m using continuesly. When i contacted with that dealer who sold me that oppo phone he stated that you should contact to service center oppo which is totally unexpectable it is his responsibility to take up such type of matter with the company. Inspite that i tried to contact with costumer care of oppo on telephone number given by them shows me busy from last two days. I again contact to dealer who sold me this opportunity phone to which he replied you should go to service centre of oppo. It seems to negligence of company and a dealer.
