Old Havana Casino support told me via chat that their time to process withdrawals (including verification) is 1-2 weeks- quite a long waiting time for an online casino.
Still, it has been 2 weeks now and the payment is still showing as 'pending' in the cashier.
After completing the wagering on my match deposit bonus I submitted a withdrawal request for $200 on the 18/08/2017 and was contacted by their support via phone and email asking for verification documents to be sent to them. After submitting them, I received an email saying they were accepted.
Please honour your commitments and pay me my money promptly.
