Vodacom wrong billing + no data on contract

Ref : A6-X3A1-EB1XZ - Logged dispute with them with regards to being charged for using xtra data although call centre confirmed that I had +_ 700mb left for june 2015. Suppose to pay 139/month but got charged +_ R245. As expected still no fix from Vodacom for problem. Changed my account to Top up then quess what. <br> <br> Ref 005T~T1WU. Vodacom scrued up again. From 1 Aug no data. Log on program report my account balance as data available. This was from 1 st Aug. Balance of left over data from prev month also gone. Phoned their useless call centre in the beginning of Aug and was told that someone will contact me, still waiting on that call. Phoned yesterday from Chatz Vodacom in Green stone centre and manager logged query via email with above ref. Once again it's now the end of day after logging query and still no response from Vodacom. I suppose it's f#@&amp
