Poorest after sales customer service ever

On the 9th of August I purchased one of your top range double door fridges from a Hirsch's store. About three weeks a the fridge has been making a high pitch ringing noise, the type of ringing noise an expensive LG fridge should not be making. We then contacted the store and were told that an LG technician would contact us. The technician came out to "diagnose" the problem. Apparently it was the compressor. Nevertheless its a week later and the fridge has started making the same noise again! We contacted the technician, who told us to take a video of the noise. So... LG I have abut 15 videos for of this noise. As I sit on my patio now, I Can hear the penetrating ringing noise. Your service has been the poorest I have ever experienced. I spent thousands of rands on one of your top range fridges but the after sales customer service is nothing but pathetic. My question to you LG is... 1. Why did the fridge not make the sound in the first few weeks? 2. Why is it that when I put the fridge off and on at the wall the sound goes away. 3. And why is it that I have to fight weeks to get this sorted? Oh, because I seem to be a ******** that just wants another new fridge?

I can send you the 15 video clips. If you would like them.

What I would like, is an explanation to all of this pathetic service AND a new fridge LG.

I will await or feedback.
