Bought a bundle thinking it was something else. Will i get refunded?

I recently bought the senrai maidens bundle, as i thought it was a limited time offer for the new tanks that had come out and i did not have those countries. I thought it would be nice to have tanks for countries i never played so i bought it (without reading the full description like an idiot). Turns out it was for the old senrai maidens tanks(of which i already own the skinless tanks and pretty much have those countries done already). I realized this after crewing 2 of the tanks and immediately regretted everything. I submitted a refund request saying how i had not touched the tanks and played them at all and it was an accidental purchase. How likely is it they refund the funds?
