Cell C *****s data

My complaint is related to the Ackermans store in town in Modimolle. This same complaint is also going to be posted on Hello Peter and Cell C since the manager at the above mention store REFUSE to help me.I bought a Hurricane Rush smartphone on 30/03/2018 that came with a Cell C special that I will get 3 GB data over 6 months in the form of 500MB a month for 6 months. But I did not get the data. So, I phoned Cell C and they said I must go to the Ackermans where I purchased the phone. I went there and the ladies at the till had no idea what to do so they referred me to the manager / supercisor called Lebogo. He also did not want to help me and said I must phone CellC. I told him I already did. He said that I must do it again since he vant and wont do anything. For 15 minutes I tried to get hold of a Cell C operaotor without success. He the VERY RUDERY AND RELUCTENTLY told me I must wait and went to the back of the store to wich I assume was a office. I waited 25 minutes and he did not return. My lunchtime was over then so I had to leave. I phoned Cell C that night again and the operator again told me to go back to the store. I asked to speak to his supervisor and held the line for longer than 5 minutes. He came back online and told me that his supervisor os unavailable and will phone me back in 20 or 30 minutes. Many days later the call did not come through. So I went back to Ackermans, but when Lebpgo saw me he again dissapeared. After 10 minutes the lady by the door told me he is busy with Fidelity and wont be available soon. I told her I am going to lodge a complain and want her name, but she told me she is only a security guard and tried to hide her name tag. But she was dressed in Ackermans clothes and I noticed her name long before. It is Palesa Matlebe. So, what on earth do I stand to do just to get friendly service and sort the fact out that I get my data? If I can't get it then I want a full refund on my phone. I will not rest untill I gheet I get it. I will complain and log and post this on all available places I can. I am sorry, but I feel it is my right since it was advertised with the phone. My cellphone number is ********** 145. The Cell C number of the phone in question I bought is ********** 370.
