RAIN incorrect billing... PEAK DATA charged for incorrectly

I contacted their customer service and requested their account details to settle my SEPTEMBER account but limited response via chat.

I wanted to know when more that 3Gb of peak data was used. The sim was deactivated before 6pm every day in September and reactivated after 11pm to limit cost. I also have a 1Gb/R50 limit set. I know that I owe you for September off-peak and have requested account details. I need any additional cost to be cancelled as your system has charged me for peak data that was used in off-peak times. There is A PROVISIONING ERROR in your system that results from backlog processing due to high volumes of data being used just before 6pm. I requested FULL DETAILS of PEAK data downloaded with times. This seems to be a **** as I managed my off-peak data downloads.
