Pathetic service

We are not receiving any assistance from hi fi Corp and pathetic service by the manager Melanie from cornubia hi fi Corp. Our TV broke which was 7 months we then went into store on the 5th March they said they will log a request for a technician to come through and sort out and let us know. Technician came he didn't even check the TV he said will let us know. It's now the 19th of march we are still sitting with a broken TV that hasn't even been taken in. The manager in cornubia is extremely rude as she kept on screaming and not giving us a chance to talk when I had to tell her to calm down, then we went into her office with the cameras in the office she tells me if I wanna be angry I must go to the front of the store and get angry, is this the way your managers are trained? This is the worst service from hi fi Corp then the manager shaylene calls us and tells us if we go and write a review it'll be them at the store that will call us back
