Mobile data canceled on 24th but still billed

On the 24th of March I canceled my month-to-month 4GB Afrihost mobile data package. I did this due to poor MTN 3G reception in the area.<br> <br> Their T&Cs say this needs to be done before the 25th when they do their billing run. I received an immediate pop-up notification that I would not be billed anymore. Shortly afterwards I received my bill for Afrihost and this indicated that they decided to do their billing run a day early.<br> <br> The reply from support today is that they won't be disconnecting or refunding me as their is an active connection - this SIM is part of my Afrihost Plus+ package and includes free 500MB data which i feel I'm entitled to use. The SIM is also in a router which at my fathers house for him to use so I don't have immediate access to it.<br> <br> If Afrihost wants to keep the SIM active then its their problem, but going against the T&Cs is also not on.<br> <br> I'm would like to know what Afrihost is now going to do to make me happy as I've got multiple Afrihost products?
