Juz fyi my frd claimed warranty fr sony sg before.

1 day post to johor supplier>johor supplier go to sg when he is free/need restock(1-2 weeks)>wait ard 1 mth>return to johor supplier>1 day pos back

Total takes 1-3 mths max only.
Total fee involve: rm20 to pos, rm50 runner fee, rm20 pos back: total rm100+-
In my opinion paid service is better (n is a more common term among all shops)
