No datat loaded on modem

Upgraded the contract and prorata data was loaded in first month. On 01 October no data was loaded as per the balance that we were pulling from Vodacom website. Contacted Autopage and was confirmed that the data was not loaded and will take 24 hours. Spoke to a supervisor who said that the data was loaded and used but despite numerous call to the Call Centre and speaking to supervisors and promises of proof nothing has materialised since 5 October. When asking to speak to a Manager the call centre cuts the call, promises made to return my call and nothing happens. Reported on their Facebook site once again promises to resolve and nothing happens. Now get told I must complete a form to get my own information. Shocking service. All I am asking for is a printout confirming that the data was loaded and at what time the data was supposedly used. simple request.
