How do you expect a script to execute reasonably on a data set if the structure of that data is NOT what you posted and on which the script was built?
The script evaluates $NF for the supplier field in supplier.csv, but in ALL lines finds "JAC" (not "DIF" as you claimed), for which no manufaturer exists, so it writes the record to the wrong_match file. Except for those "Microsoft" (and a few "Nokia") entries, that don't have a manufacturer in $3 in website.csv, so empty matches empty and thus prints to the result file.
PLEASE get your act together, correct the input data, and run the script again. Use $6 in lieu of $NF if the "JAC" field can't be eliminated, hoping $6 will always be the supplier field. Also, look for orthography in the data, like additional spaces or upper/lower case.

IGAWK(1) Utility Commands IGAWK(1)
NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
