Company won't give me full refund

<p>I am highly disappointed in your online store. The week my item was meant to arrive, you inform me that your suppliers are out of stock. You took my money for an item that wasn't in stock, without any warning to me. And when I want a full refund, as you have suggested I do, you won't give me the full amount. I paid a portion with a credit card and the rest came from my voucher. This voucher was a Christmas gift which I now lost as a result of your company. I do not wish to shop with your company in the future. I do not want an electronic voucher to purchase something else from your store. Why would I buy something after experiencing such terrible service? Now, instead of getting my Christmas gift, I'll get nothing because you won't refund me the voucher amount. You *****ed up, not me. Your terms and conditions do not apply in the case where your company was at fault. I was happy to use the voucher until you *****ed me over! As a customer, I have the right to know before purchasing something whether I will be waiting for out of stock items. Shocking! I expect a FULL refund as you messed up. Worst online shopping experience ever. I will not be recommending you!</p>
