willing to Sue hisense for faulty phone and horrible service

I bought a Hisense T5 mobile on 17 February 2018 and have the following problems with it : the phone freezes when i open an application the phone battery does not last longer than an hour the phone has problems with the speaker , calls are not audible. the phone screen randomly blanks out. Foschini obviously will not take the phone back because of the 30 day T&C's but the phone came with a Hisense warranty . I STILL HAVE MY SLIP as well as all accessories that came with this phone. i am extremely annoyed because i rely on my phone to access emails and make business calls , i cant do this when the battery only lasts an hour. i have written several reviews on hellopeter , i am even willing to post on twitter , facebook ,instagram and any other social media platform or online community where my voice as a consumer will be heard. i am not satisfied with this product and have not gotten a response from hisense as to how they as a company plan on fixing this problem. i know my consumer rights and i am even willing to take the matter to court , i want a full refund . i am not even interested in getting another hisense phone in exchange for this one because i have lost all trust in hisense as a whole and would not recommend anyone purchase their mobile phones.
