grade change request

hey, my grades for spring quarter were put in a few weeks back and one of my professors accidentally input an A- rather than an A. I won't be too descriptive, but for context, I was closer to a 100 than I was to an A-. The TA accidentally input some of my assignments as missing causing the prof to assign I received lower than I did. I emailed my prof as soon as I noticed the discrepancy with proof of my homework submissions and my homework grades were corrected, raising my grade back up above the A threshold, but my grade still shows an A- on myucla and ever since then I can't get in contact with my prof.

as much as I don't want to it seems like I have to contact someone else to speed up the process because I'm in the middle of applying to internships and my major gpa shows lower than it should be. who do I contact to do this?
