Billed for Cancelled Contract

Have 2 contracts -one that expired on the 3 August, hence gave one months notice to terminate the one contract -in fact the notice was given on the 01 July 2015. However, at the end of August ,was billed for the month of August,raised a query and was promised to be credited for the full month, as the notice was given. However, it has been a mission to obtain the refund, amidst numerous phone calls and e-mails there has been no positive responses Did a follow -up last night with Customer Care-only to ascertain that I was only refunded R 90,50, as I was apparently billed for late penalty charges,<br> This is grossly unfair in terms of the National Consumer Act, as my rights have been violated, I require my full refund as I did give the months notice. Its appeared as if Network Companies abuse the consumers as they simply bill the customer 's account as they have all their banking details but to refunded ,it is a mission .<br> Service delivery is absolutely pathetic as they do not engage with the consumer. <br>
