Poor Service

On the 9th of March we bought a Sansui 50 inch tv on promotion from Incredible Connection in Carnival Mall. A week ago the tv just refused to switch on. We took it back on 5th of July. They refused to exchange the unit. Then I asked to speak to a technician. He is still on the way to work at 9h30. I then asked for a manager. Guess what? Not in. I also asked to speak to a area manager. No they dont give out the numbers. So I asked the lady to call the area manager on the shop phone and she refused saying I must call Head Office. I asked Tech called me at 10h15. The service from the technician was good. The whole experience left me with a baf taste in my mouth. If an appliance doesnt work in the warranty period replace it. Dont always look for excuses. This is the second time I have a bad experience in this store.
