Incorrect billing not fixed!

I received a data bill on the 11th of August 2015 for R8486.48 on my *** number. On my subsequent visits to the Clearwater Mall Vodacom 4U branch where i always do my Vodacom business i was told to lodge a data dispute. The consultant called Hein, cell no *** whom i contacted on his cell to enquire as he doesn't work there anymore said \how is that possible as there is call limits on all your lines?"also led me back to the call centre. These call limits i done with him and his predecessor called Morne. <br> I lodged a data complaint with reference number S3-8G41E-EAVAG . Vodacom doing nothing untill i received another bill for R9020.96 ON 2015/10/09. Out of desperation i drove to Vodaworld and spoke to Alina Kumalo only to find no call limits and the rude guy that phoned me on 2015/10/15 that said i am not truthful about this account has only written off the second amount that should never have happened. She logged a request again with ref S3-9L921-13RFK only to find my lines locked on Saturday and CS says its because of investigation"
