Arbusers

Hello everyone,
I have been exploring the odds for arbitrage between Dafabet and Pinnacle, and I've noticed constant opportunities.
I am aware that Dafabet allows arbitrage and has no issues with it.

I decided to create an account and placed two test bets. However, my account was immediately limited. I cannot even place 1 euro bet because payout limit is reached.
It has been a month, and despite reassurances from customer support, my limit has not been changed.
No reasons were given

Do you think there is a way I get my balance back ?

Thank you
