Did You Know? NO BIS for Blackberry Z3 on 8ta

Hi, I recently purchased a Blackberry Z3 smartphone for my daughter and I. We were both on Cell C network and after some word of mouth I found Telkom 8ta to be cheaper. So I ported my number as was on the 8ta (Telkom mobile) network. The data was cheaper and the network sucked because there was continuous roaming, but I was happy nevertheless. I then purchased a BIS R59 monthly package on the (27/01/2016). I was told by my daughter I will receive a SMS to confirm the BIS being active. I waited and waited and then decided to call the Telkom call centre. To my surprise the consultant told me that the Z3 does not take BIS. I told him my daughter has the same phone, he tried help me by telling me about the phones settings. Nothing worked. He put my on hold and came back and said Telkom Mobile BIS does not work on a Blackberry Z3. I was surprised and I asked him why do we have the option to select this on the phone, why don't we get a message saying it does not work. He could not answer me. I asked him about my refund. He said \sorry sir there is no refund as the transaction already went off your account."I asked can't he reverse this he said No.I will be moving back to Cell C."""
