POOR SERVICE!!!!!!!!!!!

I received a sms from what seemed to be Cell C, my service provider, to say that I must reply with a 1 if I wanted R50 airtime and 25 sms's every month. As I have been a pay as you go customer for years who hardly ever ,this sounded like a good idea as I then will have to buy no more airtime. 4 Days later I received a sms to say that I have successfully been migrated on the day I selected and that I am now on a plan that provides me with the airtime and sms's as promised. I went to a Cell C outlet. They informed me that I am no longer a Cell C customer but a Blue Label customer and that they can’t do nothing about the situation. Who the hell is Blue Label. I never asked to be migrated and I never gave a data for the migration This is ***** and I need this to be rectified asap or sooner! I found the details on the website and called, they have the worst unprofessional consultants and ridicules processes. ALL I NEED IS MY IMEI REF NUMBER Its so frustrating taking time out of my day to call all the time and getting no JOY!!!!!!!! My insurance claim is now standing still!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
