Delay past 21 Days

I handed my 7 month old Samsung LED tv in for repairs on the 3rd of January 2015 at Dion Wired Centurion. I contacted them on the 26 January, past the 21 days repair guarantee. I was told that Samsumg repaired it but it will only be at the store on Friday 30 January 2015. Not sure if the repairs were done in China? I phoned them today and was told that products only gets delivered once a month and picked up once a month. I now need to wait till the first week in Feb 2015 for my TV. More than a month after I handed it it in. I feel this is unacceptable. Should this product not now be replaced by a new TV after 21 days?<br>
