Bad customer service

I've reported the dis-functioning of my french door refrigerator on the 21st October 2017, this being the second incident after it was fixed around July 2017. I did the rebooting as advised, called again on the 25th and a technician was booked for the 28th with an agreement of the 3 months warranty. On the 28th I received a call from a technician who mentioned a call out fee of R550.00 as they are a different company from the one that fixed the fridge around July, but i refused as i understood that i was dealing with Samsung and not their subcontractors and i was still covered under their 3 months warranty. i was advised to call Samsung again by that technician, i did call and i was told that they will send the company that first fixed my fridge to come on Monday, I made several calls on Monday and i was transferred to different people with promises to get back to me. this morning i phoned again and to my surprise, was told that the call has been logged off because i refused to pay, What's happening Samsung? the decency to call me and find out what's happening, now i'm told that the system its not working they will call me back, the same thing i was told on Monday. This is the fridge that was bought 2014 and yet i'm experiencing more problems with it than the other brand i had for more than 10 years.. i am so disappointed by the service i'm receiving from Samsung appliances call center let alone the quality of the Samsung French Door Refrigerator.
