Query: Not impressed with Amazon's digital download service

On 12/14/2010, I placed an order for a DVD and received an email stating I had a $5.00 credit for the video section of Amazon.com. This morning, I attempted to use it to purchase a movie, The Core, priced at $4.99, and I subsequently was charged $4.99 per a follow-up email and I do not know why my credit was not used. There was no place for me to input the code (12/14 email: past order entitles you to a promotional code that you can apply on your next qualifying order). The instructions from Amazon stated this: "although the price on the button will not change, your credit will automatically be applied to your purchase." Additionally, the movie did not download so I do not have that either! I requested the $4.99 be refunded to me and I will not be using the video services from Amazon.com again in the future. Compared to iTunes, I find the service via Amazon not nearly as user-friendly.
