I'm seeing comments like 'ah! but its a two year contract' but in fairness, those of us who use data don't give a hoot if it's contract or pre-paid just so long as we are not being ripped off...
If Afrihost drop double data, then your prices will be more than all other operators offerings.
Example: Afrihost Mobile 5 will become 5GB at R297 but Cell C 5GB Pre-Pay 12 months works out to R249 pm. I get 6% discount on the Cell C offering so I'll pay only R234 pm. That's around R50 pm less (R63 with my extra discount).
Now if I take Mobile 3 and add the R99 pm to keep the extra 3GB it's still more expensive than 5GB from Cell C. Of course I would get an extra 1GB but on this particular account. I've never ever used more than 5GB on that account.
Afrihost, you've got it seriously wrong! You still have a month to resolve the situation to come up with a better deal or risk losing almost every customer that you have!
