CELL C IS NEVER WILLING TO ASSIST

I sent an email to Cell C Customer Care as my Ipad could not pick up network coverage. A customer care agent contacted me and advised that i should do a sim swop and that I could purchase a nano sim from Pick n Pay for like R1 and then call in to the Cell C accounts department and request a sim swop. I followed through with the advice-went to Pick n Pay only to find that they do not keep nano sim cards. I then had to go to Cell C and pay R10 for a sim swop. It is now almost 2 months and my Ipad is still not working even after changing the sim card. There is nothing wrong with the Ipad as I can connect via Wifi which simply means that Cell C is the problem and the agents are not willing to assist
