Aiml seniors i need help

im in 3rd sem aiml and for the past few months I was volunteering full time for our college fest (8th Mile). Because of that, I couldn’t attend regular classes. Our club officially provides attendance for people who volunteered, and they have already confirmed that they are giving it to me.

But one professor (Rajesh R.M.) is refusing to give me attendance for his subject (DSA) even though the club has approved it.

Has anyone dealt with this before? What’s the best way to approach this? Should I talk to the department, the club faculty coordinator, or try speaking to the professor again?

Any advice would really help
