Still awaiting feedback from call centre !!!

I have received my fnb prepaid sim card on tuesday , today is friday. Was told that when I receive it a consultant will call me to activate it , I didn't receive any communication from anybody. Sent through a few e-mails asking for somebody to call me to assist me with it but still no response , I then called fnb personally and asked for help, and again was told that a consultant would call me. Now why does this have to take so long to do ? I mean I got the sim card 3 days ago and it hasn't been activated as yet!!!! Is it because it is free that nobody cares to help? Really disappointed with fnb's call centre!
