Various *****alant sim swops

I only have a data 3g line with Vodacom and discovered that a *****alant sim swop to a i-Phone 6 handset and talk time took place on 05/02/2015. The ***** was reported at Vodaworld (call centre) on 18/02/2015 and eventually the *****alant transaction was credited back to me at the end of April 2015. I then wanted to ugrade my data line as I was scared of ***** agani. I was informed by Vodacom in Meyersdal that another *****alant sim swop happened again on 15/05/2015 for another i-Phone 6 handset and voice data for delivery on 18/05/2015. Again I reported this to Vodaword and the ***** Department and to date the *****alant transaction has not been reversed. I have been invoncienced due to no access to a data line. I have now also received my August statement and now a *****alant laptop has been added to my account. My data line subsricption was always R167.49 per month and now with the ***** my monthly account is R1559.00. No one at Vodacom is taking ownership of this case and I demand that my data line gets actived immediately (I am using my wife's internet) and that my account be re-instated as per my orginal agreement.
