Data Network has failed twice

I contacted Cell C Technical division on the 2nd of September twice, my mobile data worked the morning but then later the day it just closed. I called and was directed to setting on my phone, we went through the whole process together and still nothing happened, again I called them and nothing happened again I then went to *147# and requested data settings after this set up it worked. Now this morning 8 September I am sitting again with the exact same issue, I have now even Factory reset my phone and I also used *147# to set up my data and nothing is working.<br> <br> this is absolutely unacceptable there was nothing wrong with my phone or my data and now suddenly I am having problems. I want this sorted out immediately.
