Worst customer service ever !

I've tried to contact Blockbuster customer service for the past week, they're not replying to my emails or answering the customer service line.
This is regarding an item I bought with them and haven't received, they are very quick at taking money though.
previously an item I bought from them shipped to me without the proper amount of stamps where I had to pay to get the item from the post office.

Do Not Use This Company !!!
