Bad service Mercedes Benz Menlyn

I bought Mercedes C*** model at Mercedes Benz Menlyn branch in July 2017. The leather on the armrest driver side is cracking so bad that it also affect my clothes. I have reported the matter with the dealership on the 4th November 2021 and was informed on Tuesday, 9 November 2021 that they will request the quote for me to pay since the warranty is only for 2 years. I then requested to speak to the manager who mentioned that they will wait for Mercedes SA to respond. However, there is no guarantee that Mercedes SA will agree to fix the problem. I am really disappointed with the quality of the leather used on the armrest.
