Upgrade

I upgraded one of my contracts on the 11 of November 2017 to a Smart S+ package which included FREE OF CHARGE once off 20 gig of data w.e.f 1st December 2017. I did not receive this 20 gig on 1st December for this contract and after 2 days of trying to sort this out with Vodacom's customer care they told me to go back to the vodacom shop at which i did the upgrade since they could not assist me telephonically. I then called the branch and they logged a query, the 20 gig was then added but I was charged R999 for this. Despite the fact that we didn't get the data as promised on time and spending time trying to sort it out, they end billing me incorrectly for the 20 gig as well!!! I find the level of service from Vodacom to be EXTREMELY POOR. Get my account sorted out asap and reverse the R999.
