No Electricity

I tried to purchase my electricity using cell phone banking and the transaction did go through but I never and have still not got my vouchers. the first was R50 which went through but no voucher. The second was R250 which show that it went through as I received an sms from my bank , but I still do not have my vouchers. Now this morning I purchase it cash at the garage and I am trying to redeem my voucher and it is giving me an E150 error. My electricity is now on 0.2 and there seems to be no nope of coming right on my end. I have appliances that need to be running 24/7.. What's going on? it may be small money but I worked hard for it.
