I never got restricted by Betby. I have been limited by Betby.
That doesn't mean anything, really. In all sportsbook I've been limited they let me withdraw without any problems.
So, the reason is crystal clear here. You are trying to bypass the limit of the odds provider by creating an account in a different sportsbook of Betby provider. It is obvious that you will face issues on Betby providers sportsbook in the future. You have been limited by the odds provider, not by the specific sportsbook. Betpanda won't refund your deposited funds. It is written in their terms, and you had agreed with the terms during registration.
14.1 Conditions for Returns
In order for the Betpanda.io Balance to be eligible for a return, please make sure that:
The Betpanda.io Balance was purchased in the last 14 days. The Betpanda.io Balance was not used in wagers of any kind. (this means after the purchase you did not do any actions involving Betpanda.io Balance on Your Account)
Unfortunately, we can't do anything for you. Some clauses of Betpanda terms are really unfair for the users. Different betting sites have different rules. Stop playing in the sportsbook with Betby odds provider.
