That's the Dev fee, which is used to fund the team's projects as there was no ICO. However, it should only have been taken once. NOT ten times.
PLEASE contact the Dev team via Discord (there's a 'Support' channel there that you can post in) - if you don't have an account, it's easy to set one up - they will be able to sort you out and put things right there.
