Ad Hoc Data Purchased Does not Reflect on Invoice

During December 2015 I purchased 3 ad-hoc data bundles via Altech Autopage's call centre, <br> During January 2016 I received my invoice. None of the data bundles purchased reflected on the invoice - I was therefore charged at standard data rates.<br> I contacted your call centre on 25 January and explained the problem to the agent. He checked my profile and acknowledged that I did purchase 3 ad hoc data bundles and promised that the invoice will be sent back to Accounts to be rectified. I asked if my line will be suspended in the meantime, he promised it won't seeing that Autopage made a mistake.<br> <br> I am still waiting for the rectified invoice. My service has been suspended 4 times since 2 February. To re-instate my service, I have to contact your to your unprofessional unhelpful call agents and explain over and over and over again. Please rectify my invoice and email it. Please STOP suspending my services in the mean time. I can not be held responsible for YOUR faulty billing. Fix it.
