Terrible service from Vodapay

I usually purchase water & electricity on the Vodapay app and the process is seamless. Last night I tried to purchase electricity, the payment went through however, on the app it says unsuccessful. Made another purchase again this morning and the same thing happened. I requested to chat to someone and was told that the system reflects a refund and will take 7 days to clear. Lerato was great help and even gave me a courtesy call. Now I must be inconvenienced. I'm sitting here with no electricity and no money to buy electricity because I must wait 7 days for my money to reflect. No one can tell me what the issue is and why i wasn't able to buy electricity. "sorry for the inconvenience" is not going to keep me warm in this cold weather.
