7 weeks later and repair still not done

On 29/12/2014 I took my Sinotec TV into Makro to be repaired. I had specifically chosen Sinotec because they have a 5 year warranty (TV 18 months old). I received sms's to indicate it had been submitted but nothing since. Now 7 weeks later I have been trying to find out where it is and am getting nowhere. I have been given the runaround. On Friday was told it would be back by that afternoon or Monday morning. Today all I can get is 'it isn't back' on 3 occasions, after hanging on for 10 minutes, the call just cut off.
