WRONG CHOICE PURCHASING HISENSE

Good Day

Trust that you are well.

I have purchased a Hisence U962 in May. I started using in June and found the battery die within couple hours. I had booked in the phone for repairs on June 12 and i received the phone back on 30 July. I charged the phone last night and today around 10 i switched the phone on. the phone did a wireless update. There after i installed whats app and share it only. Within couple hours the phone battery is down.

How can i use a new phone that dies within hours.

Sorry to say this is my biggest mistake purchasing this brand.

Thank You
