WTF: "Payment not authorized. Exceeds withdrawal limit."

[nicroets]

I recharged 2 sims with R50 each today. The second one gave me "Exceeds withdrawal limit". I still have more than R1,000 credit on my card, so that can't be the problem. Does their system only allow 1 recharge per card per day ??

You should have recharged your account with R100 and transferred the airtime to another number - instead of having duplicate orders.
