No regard for customer care

I recently bought a Sumsung s8 from MTN dandy in branch. In the past Sumsung offered a free screen repair within 12 months of purchase through ADH. Sumsung has recently changed their insurance to a new insurance that forces client to pay for screen repairs. I called Sumsung call centre to arrange to get my s8 screen repaired and I was told that I will have to pay R4500 for this as my phone was out of warranty. How can a 6 month old phone be out of warranty. No regard for client care anymore
