Debit Order not cancelled

<p>Mondo never provided me the service, so they agreed to terminate the contract. But every month I am still seeing the debit order going off!!!! I am still paying for a service I don't have. If I email Mondo nothing happens, the only time they respond to me is when I log a hallo peter complaint. People stay away from this company. They sell Telkoms contracts but once Telkom has your banking details Mondo cannot do any query or cancel the debit order on your account..... They are the middle man for Telkom and its not working..</p>
