No responce or Resolution

On the 31st July 2015 Autopage debited me R 381.10 . I did not have an invoice for this amount and wanted to know why the amount was higher than normal. Since then I have mailed, phoned and mailed again to try and get some answers. I have 5 references from Autopage all that have been closed and a new call opened. Their call system is pathetic. 5 times I have had the phone put down on me when they answer. I have tried to be polite and nice but cannot stand for this poor service any longer. I hope this gets a response.
