Cell c took R399.00

I bought data via pay fast on the 26th of November for R399. 00 I bought this via their website. The data I bought was 7GB and 10GB NIGHT. I POSTED on their social media and told them the experience. They advised they would call me. I waited on the morning of the 27th which nothing happened. I decided to call them. The first agent couldn't help... 2nd nothing... 3rd agent dropped my call. I then went back and forth on social media Facebook all day today. I even asked them what they are investigating if all they do is tell me they are investigating but they don't call me. After I mentioned to them after spending more than 2 hours on the phone (when I called them) a social media consultant said she was busy with it. It was just a 1Mins call. They then refferef me to the back. This money was paid via pay fast to them so the bank (Nedbank says they will charge me 250 to do a recall and I'll only get 150) I called cell c again at 12.55 pm the manager told me that it is a lie and that cell c should not be charging me R250 and that he wants to escalate this process. This is ********** - do I have a case if I log this with the lawyers? No one can answer where my data is they just say that they cannot give me my data. Is this legal? I just want to know so I can take this further. I spend so much on airtime all year for years now. I'm now sitting with 0mb and I asked them what do I do in the mean time? They said they don't kno. So basically I'm forced to buy data again no ways. I'm even on the line with the manager now who doesn't seem to want to help me
