Overcharging on Account after Upgrade

I upgraded my contract with Autopage in October 2014 and switched from a Blackberry to a Samsung. the charges for the Blackberry BIS continued, despite the contract upgrade. The call centre consultant (Thandeka Mzibi) today told me that I was supposed to inform the store where the upgrade was done, to cancel this service as Autopage cannot assume that the service must be discontinued after the upgrade to another device. However, my international roaming was cancelled with the upgrade despite me not requesting for it to be cancelled. To this the consultant responded that they do not charge for this service therefore it gets cancelled with the new contract. Be careful customers!!!!! Autopage just wants to make money and is NOT treating its customers fairly. I've been with Autopage since 1999 and this will be the LAST contract ever with them. Nowhere was I notified nor informed that I needed to cancel the Blackberry BIS facility. I \assumed"that since I have another device and am not using the Blackberry BIS"
