Your data appears to have variable number of columns. The code you wrote will work if all rows in your input file has exactly three columns.

But if that is how your input data is, then one approach is to create an associative array with index/key by removing the last column:-
Code:
awk -F\; '
        {
                idx = $0
                sub(/[;][^;]*$/,X,idx)
                A[idx] += $NF
        }
        END {
                for ( k in A )
                        print k, A[k]
        }
' OFS=\; file
