Out of bundle rates - overcharge

Good day<br> I contacted the Vodacom business assistance helpline and spoke to Presley. I notice that I have been charged with out of bundle rates for a few months without receiving a notification as can be seen on the attached copy of the Cell nr log. The last message I am aware of was send on 20 Sept 2014. See last message received Sender: Vodacom SMS,Date: 09/20/2014 20:05:21,Alert: Your Vodacom data bundle on ***... has run out. Out of bundle rates now apply. <br> I called Vodacom assistance *** on 21 Feb 2015 at 09:30 and spoke to Presley. She informed me that Vodacom did send messages, and that I should log a call with the Admin dept to apply for a refund for the out of bundle amounts charged.<br> When I took out the contract I asked that the account be capped. Obviously that has not happened, or app**** for a short period because I did not initially get charged for out-of bundle rates. Presley informed me that I should return to Vodaworld where I took out the contract to verify this. It is upsetting that I have to pay out of bundle rates for a contract that should be capped and for which I do not receive alerts.
