Non-existent after service to customers

Hi. So frustrating. Called the hifi Corp call centre. Spoke to Brandon. Explained to him about my Hisense 50 inch smart TV that was purchased only last year. The screen is blue & no picture can be viewed. Says the closest branch will have their repair centre guy come view the tv & take it from there. Brandon transferred me to the South Gate branch. A lady who sounded bored & half asleep (I regret not asking her name) answered saying she will transfer me to customer care after I explained my tv situation to her. Thereafter I heard a beeping sound & call drops. Pathetic service. Pathetic customer service HiFi corp! Come on! We purchase from you with understanding that customer service is important but you have pathetic employees who are useless!!! Please assist asap as my television needs to be seen to. Thank you.
