Angel Broking Option Selling

Can someone please tell me why does Angel Broking credit the premium collection the day i take a long or short spread. Once I took a spread with a potential premium collection of 750 Rs, but even before squaring off my position, they credited 696 Rs to my account. I went on to book profits on thursday but according to my estimate my profit should have been around 610 Rs after all charges but they have not deducted any amount even after 2 days. Please let me know why is this happening.
Thank You
