I bought 5 times without knowing that the razer gold cod mobile cp campaign is limited to 1 time per person and I could not use it. can I get a refund?

I bought it without knowing that it was a cod mobile cp campaign and it was limited to one time per person.
After purchasing it, I realized that I could not use it and the purchase price is too expensive at 10,000 yen, so I want a refund.
Please respond to this request.
