INCOMPETENCE

We bought a 55" TV Sansui last year September. 3weeks back it just switched off the screen. So I took the TV to the shop so it could be fixed at Festival mall branch. I was told cos it's more than 50" TV then we must take back the TV home so it will be fixed at home. The TV was booked. Today the technician, Walter came, with his family in the car. Switched on tv and said cos the TV doesn't show screen we must take it back to the shop and left. My concern is I explained to the lady what the TV does. And I had the TV with me but was told I must return with the TV at home. Today the technician just came in for 2min,with no tools on hand and with his family in the car. He tells us we must go back to the shop with the TV. Mind you that we have been staying without the TV for 3 weeks. And does your staff know time is money considering we must spend petrol again to send back the TV. Even the TV for lasting only a year does that mean Hifi Corp sells displays? I'm not happy at all.
