Worst Service

After getting a Brand new Samsung S6 Edge it was faulty from the start, took it in for repairs in Roodeport, got it back 2 weeks later still faulty. Then took it to Samsung on Nicol way... they confirmed it was faulty and that it would be replaced..... 15 days later, no one knows my replacement order number, i keep being told i will be called back and i never am.... i have to keep calling every day, and NO ONE calls back. This whole service from Roodeport to Nicolway has been disgusting! ! Am i ever going to get a phone....
