Answer 1

Option 1. You can add unique values combination in migration.
Schema::table('your_table_name', function (Blueprint $table) {
$table->unique(['phone ','customername ']);
});
This won't let you insert same combination values for these column combination, however it also throws error stopping you import function.
Option 2 (Better).
Check if value already exits and ignore import for that column.
$old_customer = Regiter::where('phone', $row['phone'])->where('customername', $customername )->first();
//Inser only if customer not found
if(is_null($old_customer))
{
//INSERT QUERY
}
To decrease number of query you can pluck name and phone with single query or use any other optimization tricks.
