I got 2 charges of the same product with different num. of order

Hello, can you help me? I bought the PlugIn of Unlimited Logo Carousel – Unlimited Site License. When processing the payment, I duplicated it with a payment card and paypal form.
I got 2 charges of the same product with different num. of order:
Order # 4376
Order # 4375
I know it will be complicated to ask for a refund of a payment, but maybe you can send me another plugin
in advance, thank you very much, I do not speak English, I am translating and a thousand apologies
I am waiting for my email is twitter.rolando@gmail.com
