Repair ****?

My Samsung Gear sport broke. It was still under warranty so I gave it in to the Centurion branch repairs department. They said it would take 6 - 8 weeks, and 6 weeks later I get an sms saying there will be cost involved to fix the watch and to call Makro national hotline. I call the hotline and they tell me to call the centurion store as they cannot access my info, 100% understand. I call Centurion store and the person tell me it will cost R4700 to repair the watch. The only info they can give me is that it has liquid damage which isn't covered by warranty. Obviously I want to fight the warranty claim, so I message Makro of Facebook and ask for more information. The only information they can give me is that I rejected the quote. I go to Makro centurion and ask for a report on how they determined the extent of the damage, they can ONLY give me my quote again. I go to Samsung who is happy to help, but they need a report on the extent of the damage. I message Makro again on Facebook and get told there is no report as the watch wasn't repaired. I specifically asked how they then determined the extent of the damage to quote me, and only get told that I was already informed there is no report. I ask for my watch back, 4 hours later my watch is ready for collection. Why does it take 6 weeks to send my watch to Samsung but 4 hours to get it back... Not trustworthy at all and I won't ever buy electronics from them. Apart from everything else, in the process I must have phoned the branch 10 times, they only answered twice.
