Hi Payal
It is very clear if it is mentioned in the policy you should adhere to it. As you said you availed more than 2 days leave before that so it is clear that there is no such policy.
In case if they have amended the policy the same should be conveyed to team so you have rights to take the issue to the concerned person (i.e., front office executive).
Have you got the leave approved by your immediate manager if yes, you can communicate through him.\
Coming to discussing salary part is a serious issue, first you talk to front office executive if you find no changes you should take the issue to the manager and to the MD.
