Unauthorized debit order

My money was taken twice from my account and I didn't even authorize the debit order. The agents **** to me by telling me that my money won't be touched unless I agree to it via phone call. I didn't recieve any phone call, but my money was debited from my account not once but twice. I tried disputing and stopping the debit order, but it couldn't be stopped nor disputed. Two mountains I ask you kindly to fix this mess. THIS IS STRICTLY UNPROFESSIONAL !!!!!
