2 weeks old amplifier not working

I bought a Sansui music system on the 3rd of February 2016 online, collected it at the Beacon Bay store on the 4th of February 2016. On Sunday morning, the 14th February, the amplifier has no power. Now I've just been informed of a 7 day swap out policy. Since this happened 10 days after I collected the unit, I have to wait 21 days for the unit to be repaired. This is a bug inconvenience. The unit is practically new, and now after being repaired it will be as if I bought it second hand. I haven't even enjoyed this because I've been busy, yet it's already in for repairs!<br> <br> I am NOT impressed at all!
