Afrihost - limited internet service

<p>Bought a Xiaomi phone from Afrihost - trying to put prepaid airtime on, but it says I don't have enough spend on my account - I can only spend R5000 per month and, because the phone cost R4670, and my monthly subscription is R1760, I have exceeded my allocation. Trick is, all transactions with Afrihost are paid in advance by credit card. They have kindly increased my spend limit to R5400, but my spend for December is already R6430. I have a new phone that I cannot buy airtime for.</p>
