No recourse on handset that stopped working

I have a relatively new Samsung S6. A little over a week ago, it started rebooting itself over and over.<br> <br> It has always been in its CAT protective case with the additional class screen and in mint condition.<br> <br> I took it to Cell C where the technician told me that it was a software problem. He tried some of the special boot options, but nothing helpe<br> <br> Now CellC informs me that there was liquid damage (there most certainly was not - if there is any liquid damage it would be from the humidity of my breath of sweat of my ear!)<br> <br> They say there is absolutely no recourse for me. I am not able to talk to a technician or follow up the facts. My phone was mint! <br> <br> The call centre agent informed me that she can put me through to her supervisor, but that I will be told exactly the same thing.<br> <br> My apparent only alternative is to reject the quote, take it to Samsung myself, and then get a second opinion.<br> <br> The problem is this. I looked up ' looping boot' on the internet, and apparently Samsung S6 has this issue (there was no other problem) <br> <br> How do I know that, if any liquid damage was responsible, it was not caused by the technitian at Cell C?<br> <br> The CAT case is very protective, this is just not on!
