Inconvenience by Faulty TV

The TV was bought in Jan 2016 EL Hi Fi. It suddenly stopped showing visuals. The store has taken the TV in for repairs it is unfair that my family must wait 21days for the return of the TV there must be an interim plan. It is even more disturbing that I will possibly be liable for future repairs if the TV right now is faults just over a year meaning I can only protect myself by an expended warranty something I would not even consider if the TV was not faulty. Hi Sense and HiFi must have a plan for my family in the 21 days for repairs even more wrong is that your company expects that the TV can be fixed 3 times before I can get a new trusted TV. I am utterly dissapointed and livid that I must experience this ... ********** I need a response and suggestion
