Electricity voucher not received

I purchased R100 electricity voucher at approx. 8am this morning. The money was debited from my account but I haven't received the message with the voucher code. I usually receive the voucher code for R100 along with another voucher code with free/complimentary electricity. I double checked that my cellphone number was set correctly. <br> <br> Pls send through the two voucher codes to my cellphone.
