Warranty issue and poor service- Samsung South Africa

I bought a pair of brand new gear icon x 2018s while traveling and a month in, the right bud has stopped working. I have the proof of payment and everything but samsung South Africa will not honour or assist me with the 1 month old product as I bought it overseas. I took it to a samsung repair center MM all electronics and they would not honor my warranty. They wanted to charge me R1800 to replace the right bud on a product that costed R2000. This is unacceptable. If Samsung South Africa is unable to help me with my product in warranty at least they should be able to charge realistic pricing and not try to rip me off. Very disappointed. I would not recommend using MM all electronics or the samsung call center as both have very poor service. In addition I was told by the samsung Reps that earbuds have international warranty similar to Samsung laptops. This was however not true. I am very disappointed with Samsung's service and customer relations in general.
