Autopage
Autopage ridiculous with out of bundle data rates

I have a data contract of 2 Gig per Month at Autopage, last Month I went over and used 2.9 Gig,
I was changed R770.05 Vat = R877.86 extra (for so called out of bundle data rates) for just more than .9Gig extra used.
This seems ridiculously expensive; I will not be renewing my contract with Autopage when this contract terminates.
The contract can only be changed to a top up contract after the first 3 Months, so for the first 3 Months there is no protection if one goes the over the limit.
