Trending @Infosys; Salary after Promotion

I got my promotion letter ( from SSE to technology analyst) on march 31 2025. It was mentioned in letter that it is effective from January 1. I also got general hike on February 2025. In that also it was mentioned it is effective from January 1. But the promotion hike i got was calculated from December month salary( before feb hike)

I was getting 4,16,000 lpa. After feb hike it was 4,47,000 lpa. But after promotion hike. It was just 5,12,000 lpa which also includes performance bonus. Is there any possibility to increase my promotion hike?

Few people who got the same role change by 1st week of jan, for them too it was mentioned that it is effective from Jan 1. But they got February hike too. But me who got the same promotion letter in march, my feb hike is not included. Is there any possibility for salary adjustment?
