HI,
I did the mistake of paying interest but for my relative flat in tower A at 7th floor, i told him not to do the same mistake as i observed they are charging heavy interest on everybody so that after negotiating and getting humiliated people will ask no question further on high maintenance as his her interest is lowered by builder. they are taking Psychological advantage.
I suggested my relative to mail them in written that prove if any written demand was not paid on time, if yes then will be ready to pay interest or else not and will not proceed futher if it is not waived completely.
It worked and they waived all heavy interest chanrged to 0.
Regards,
Sanjay
