Message From Customer Service
Hello Mr. Stagnite

,
My name is Luis, from the Kindle Customer Support Department at Amazon.co.uk. I've picked up your e-mail today and I'll do my very best to help you with your query.
Thank you for your kind reply providing confirmation of the replacement Kindle being purchased. Once the payment for this delivery is fully processed, we will proceed to refund your 20% discount, as per our promise on our previous communication and will send you a confirmation message once issued.
I have set a follow up, so we will get back to you as soon as we have further information or an outcome for this situation later this week. This because there is a 48 hours waiting period after an order is delivered before we can process any refund on the order.
If you may have further questions, you can also contact us over the phone or via chat.
and earlier:
If you are a consumer, you will also have consumer rights and the one-year manufacturer’s warranty is provided to you in addition to these rights and does not jeopardise your consumer rights in any way. This means that if your Kindle is faulty, you may be entitled to a repair or replacement from the retailer.
