Samsung and Celcom pour service

I redeemed a voucher on Samsungs website for my new phone. Cover was in stock and got an email that delivery would be in 3 to 5 days. a week later i call the number on the email, and got the news that they never had stock......requested a refund and got less back that what i paid..how nice is that from a global company that apparently cares about their customers.
