Cancelling/Returning duplicate order

Hello everyone, I recently ordered a razer core X chroma. When I ordered it my browser crashed and, since I paid with paypal by direct debit (this will come up in a bit) I didn't see money taken from my account. So I made the order again, this time with credit card and it went through. When I logged into my account I had made two orders. I used the contact form on the website and the support email and received a response from neither. So, when I saw a pending transaction in my account, I cancelled my direct debit to paypal. Both orders were shipped yesterday and are coming tomorrow. I'll update on the status as this goes along. Basically the current situation is: I have 2 razer core X chromas coming. I have paid for 1, but paypal might charge my card for the 2nd one Razer is not responding in any way So, knowing what I did was very stupid and I should have checked my account before reordering, what should I do? Should I return one of the 2 cores? What will happen with the payment in that case? I will be so glad if anyone can help in any way because I am very confused... Thanks
