Out of bundle tariff rates/bad customer service

On the 15th of March 2016, I raised a request to Vodacom to correct the tariff rate at which I am being charged for out of bundle rates. I have called Vodacom over 10 times since I reported the issues and also emailed Vodacom without any result. I have spoken to countless consultants who all assure me that the problem has been escalated and will be resolved but no one responds to me with a date when this will be resolved or whether they understand my concern. <br> <br> The details<br> 1. I am currently on a Smart S package with a 3GB recurring data bundle. As a result of the data bundle, I should be charged out of bundle rates of R0.50/MB but am currently being charged data at R1/MB as OB postpaid rates under a 3GB package.
