POOR Service delivery from online department

I am disgusted with the quality of service that I am receiving from your online department. it took them nearly a week to cancel my online orders, they did it eventually but I got no refund. I paid with my Mr price card, and my account has not been credited with the amount, nearly R1000. Poor, poor service, no one gets back to you, and store is not even attempting to be helpful, not responding on my emails either. And I am not allowed to speak to area manager. Call centre is working remotely, but no response on all their on line platforms.
