Second hellopeter complaint for the same issue - missing data

Since my initial complaint, we were told that for some reason only one of my sons' contracts was renewed on 15th December 2018 and that the other child would have to wait for 27th January 2019 for his contract renewal. We were promised the 2GB data for six months and the regular 500MB of data for the two year period. It is the 28th and my son has received 300MB of data, not 500MB and there is no sign of the 2GB. I can't put up with this type of service.

My initial complaint on hellopeter is as follows;

After renewing our sons' contracts with Cell C at the Greenstone branch which in itself was a problem since some employee had taken it upon themselves (**********ly so) to renew their contracts on our behalf without our consent, we have received the first bill which is way above the agreed amount per contract. Our one son hasn't been receiving the 2GB free data he is supposed to receive and I cannot get anyone to help me. I initially mailed customer service on 7th Jan regarding my issues, I received an automated response with case number 190 ********** 56. Supposedly somebody would contact me within 1-2 days. Since then I have called 135 and left my 2-minute voice message (followed by the hash key). Still no response. I have emailed again once on the 10th and twice on the 11th. Again, nothing.
