Pathetic Service

I called Cell c on Saturday,28.02.2015 at about 13:00.All I asked for was a sim swop and I was advised to call back with a sim card that was not ricad so it can be done.When I called back I was advised that the department to assist me is only available during working hours Monday to Friday between 8 and 5pm.The first consultant I spoke to told me I must make myself available as I told her I work in a call centre and cannot answer my phone during working hours?Is that a way to treat a customer?Speaking over my voice and shouting.Today is Wednesday and the sim swop is not done! Well done Cell c,this is one customer you are surely going to lose!
