Battle to Rica RAIN sim card

I've paid R479 upfront. I've tried to rica. When I go back to see whether the sim has been activated, I see a message saying the ID and address doesn't match. I'm using my ESKOM account. I've done this twice and both times I get that message. An ESKOM account is sufficient proof of residence. So now I'm paying but cannot use the sim. Seems to me like a moneymaking scheme - taking your money but withhold to rica the sim. I reallyneed help with this. This sim is for my son studying in Potchefstroom. Everything is online at this point in time. We chose RAIN because of it's affordability but seems to me I must cancel this sim and look for another service provider.
