Use a hash to store the votes. 
my %votes;

my $file = 'vote.txt';
open my $ih, $file or die $!
while (<$ih>) {
    chomp;
    my ($user, $count) = split ',';
    $votes{$user} = $count;
}
close $ih;

$votes{sam}++;

open my $oh, $file or die $!
for my $user (keys %votes) {
    print $oh "$user,$votes{$user}\n";
}
close $oh;

On a side note, your code wasn't working because you weren't outputted a return for each record:

# From
print VOTE $user[$count]."|".$vote[$count];

# To
print VOTE $user[$count]."|".$vote[$count]."\n";
