Mistakenly did force cancel order, What should i do?

Ok, there was an order.
Due to rush, i didn't want to do it.
I was thinking to cancel it as mutual agreement.
And the already selected option was of force cancel order and i didn't know what happen and i click the submit button and got -rep.
Please Help me Regarding this.
It was done mistakenly!
