Account still not cancelled/Non-responsive staff

I phoned the Altech Autopage call centre to cancel my contract on 13:07 30 March 2015 (***). I requested that my number be moved to prepaid as I will be porting out to a new service provider. The call ended with confirmation that the month of May I will receive my last bill. <br> <br> With this information, I app**** for a new contract but the port took just over a 6 weeks to go through - reason: The account was never changed to prepaid. After hours on the phone, the port has finally gone through but I received a bill from Autopage for the month of June and suspect it won't be the last.<br> <br> The past 2 months I have requested, multiple times, the recording of my conversation with your operator on the 30th of March. I did not take note of every call (easily over 20 made), but the calls that weren't dropped after holding for 20 minutes, were answered answered by operators each giving me new information every single time, stating that I will be contacted with regards to the voice recording in question but, again, no contact has been made (e.g. Spoke to Zahir on 20 May ***).<br> <br> 1. Help to immediately cancel my contract<br> 2. Credit me with this months debited amount<br> Thanks
