Requests for refunds are very rare at our website. However, if there is any request for refund received, would be subjected to verification and will be accepted if proper production of adequate proof is met. It would be better if you tell your full requirements and expectations clearly to tutor regarding your homework or assignment and attach lecture notes or study material or book reference related to your work so the tutor can understand better about your work and your requirements. These precautions minimize the unnecessary problems to a great extent. If you have any question regarding the solution given, would be provided to you without any extra cost.
