Rude customer service

In December, I purchased a Samsung from mr price. 4 months later I crashed my motorcycle and ended up crackling my phone's screen. According to my warranty that comes in my box, the first screen replacement is free. So I went back to Mr Price where i bought the phone and asked if they would send it in for repairs due to the warranty still being in tact. Once I got there the manager looked at me and said will not book it in due to physical damage. I explained to him that the warranty is still in tact and would like my phone to be repaired, he then rep**** that it's not his problem and laughed in my face. I spend a fair amount of money with Mr Price and was not expecting this type of service.
