Autopage after sales service very disappointing

I am still waiting for Autopage to come back with regards to the data usage dispute on the date of renewing my contract (pending since 08/05/2015) ***. I did receive a reply on my last HelloPeter posting but it has now been a week. I have been following up frequently with customer care and sometimes I get disconnected for no reason. Daily calls to accounts have now been escalated to technical department. However, after their efforts line still suspended - really frustrating! The monthly rental is paid and up to date and only the dispute amount outstanding. The lady at accounts keep reminding me that I have arranged to pay the amount at the end of the month ... which is not correct. I will pay as soon as they can prove that said data was downloaded onto specific computer - we can offer it for forensic testing. I was informed by a consultant on Tuesday, 12 May, 2pm that the MyLimit option (that I have been paying for over two years, does not work on data contracts?). From the 28-30th of May we never received an alert SMS that data ran out. The friendly &prompt service to renew my contracts (10/10) has now dropped to a 2/10 Autopage after sales customer service. Disappointing!
