charged twice for klwp pro

Hi, i bough KLWP pro key on 23. september this year. Amaizing app. But there is a problem because as I can see you have charged me two times for 5.85€ according to my m-bank app. I dont know if that is some bug but I clearly saw that the cost of KLWP was 5,85€, not 10,70€ as you charged me 2 times for the same.

If I knew that you will charge me 10,70€ i would not buy your apk. That is not fair from your side to show it as 5,85e app and charge double.
