Vodacom failing to deliver service

I recently called the customer care line to assist me as I do not have access to certain web sites and get a message from vodacom saying \Sorry Access denied, You don't have permission to access this page. For assistance, please call customer care on 082111 free from your Vodacom cellphone.\" I explained this to the call center agent and also provided some of the restricted web sites [URL Removed] [URL Removed] [URL Removed] She could not assist me and promised to call me back and this never happened. I then decided to go to the walk in customer care center @ Vodaworld on 15/03/2016. Again they were unable to assist and logged a ticket ref number INC***. On 16/03/2016 i received an SMS from Vodacom to ask if i was happy with the service received to which I rep**** No. The following day i received a phone call from Vodacom to ask what the problem was and again I was promised that they would get back to me with a resolution. It is now 10 days later and still no feedback or way forward to resolving my issue. I pay lots of money every month for a service that does not work. Could someone please attend to this and get it resolved ASAP"
