Refund nightmare....Poor client experience

I am totally disgusted with RCS/Spitz and their customer service. I accidentally paid money into my spitz account. I needed to pay R0.79 to close my account. I phoned them and they advised that I must send proof of payment/bank statement showing the money paid into their account with a copy of my ID. I did this and no one phoned me. I also phoned in twice and the phone was put down in my ear!!! I told them I URGENTLY needed the money refunded to me. How funny is that when you owe them money they very quick to take your calls or phone you BUT when they must refund you it is a nightmare..!! I want to know when my DAMN money will be refunded!!!!! What ****ty experience this has been.
