Autopage billing issue

Since the takeover from Nashua Mobile to Autopage I have had nothing but poor service and constant issues with my contract with Autopage.<br> <br> My first issue is that an amount of R3000 was debited off my account on the 31st of October without sending me any statement/invoice - only a blank email. <br> <br> When I queried the huge bill this morning I was told that Data cannot be capped per month as it is an open line. I have a cap of R750 on my contract. To my surprise this morning my phone was disconnected, and when I queried this, it was due to the fact that I have exceeded my cap!!! I can not make any calls, whatsapp or send and receive emails.<br> <br> So they are in fact able to block the phone when you have reached your cap, yet I was billed R3000, when but they were unable to notify me or block my usage when I reached my cap. How does that make any sense?<br> <br> further to my agony - when requesting to speak to a call centre manager/team leader, no one is available. <br> <br> Reference number of my call: A***.<br> <br> <br>
