Hisense T5 HORRIBLE PHONE ,HORRIBLE BATTERY LIFE , FREEZES AND NEITHER HISENSE NOR FOSCHINI HAVE DONE A DAMN THING ABOUT MY COMPLAINT

i bought a Hisense T5 on the 17th of February 2018 , its the most useless phone ever. the battery takes over 4 hours to fully charge but battery life is depleted within an hour of just checking emails , the phone constantly overheats , the phone constantly freezes when i try to open apps. i am beyond unsatisfied with this phone , cant even return it because i bought it over a month ago , it pains me because i spent so much of my hard earned cash buying this phone only to be this dissapointed . its no better than my old s**** that was giving me issues , actually my old phone functions better than this and it had serious battery problems..i left that only to buy one which is way more worse. i do most of my business on my phone , i constantly need to access emails and make calls , but how does one go about it when my battery wont even last an hour? Hisense needs to do something about their faulty phones , i have gotten absolutely no assistance ,not even from Foschini where i purchased the phone. am i now expected to reach into my pocket again and take it to get fixed or buy a new battery? when i have already spent so much on buying a new phone that barely works? and what is to become of my business in the interim while my phone is gone in for repairs ? Am i just supposed to stop everything , have no communication and wait until whenever i get the phone back ? this is absolute nonsense , i will tweet , post on instagram , facebook and anywhere else i can give a review until something is done about this. I am well aware of my consumer rights and will not let this go until i either have a new phone that operates without any problems or i get a refund!!!
