Code:
A123, valueA, valueB
B234, valueA, valueB
C345, valueX, valueY
D456, valueX, valueY
E567, valueA, valueB
F678, valueA, valueB
G789, value A, valueB


Replacing file1 and file2 in the awk seems to give correct result.
Code:
awk -F, 'NR==FNR{A[$1]++;print;next} !A[$1]++' file2 file1 | sort
A123, valueA, valueB
B234, valueA, valueB
C345, valueX, valueY
D456, valueX, valueY
E567, valueA, valueB
F678, valueA, valueB
G789, value A, valueB
