Not getting service according to contract

<p>I renewed my data / router contract with Vodacom at the end of March 2017 in Witbank, at the Saveways Crescent Vodashop, and it was done. The renewed contract had 4 Gigabytes, (2 Gig for any time, and 2 Gig Night data) for R139/month. For the month of March I did not receive my Night data, and I thought it was just me not seeing it. For the month of May, I checked my data loaded, and there was no 2 Gig Night data. I called Vodacare (111) for them to check, they said it's not loaded (or actvated), I must go to the branch. I went to the branch (Saveways Crescent in Witbank) last week on Friday (05 May 2017), and they took my details, and send an email to somebody (or department), and I was told they will come back to me. It's now over a week, I still haven't heard anything from Vodacom. This is really disturbing.</p>
