FNB service drops to last on the list

I took out 3 cellphone contracts with FNB. After less than a month one of the devices became faulty and I had to return the device. An order was made out for a replacement of the device. Its almost a month later and I am still waiting for the device. I have phoned several times but none of the people I spoke to was able to help or tell me what the status of my order was. Even spoke to a line manager (Randy) at smart devices. He promised to phone me back. Did not so he can shove that promise in his ass or better in his managers ass. Pity FNB says "How can I help you". They should change it to "How can I help you **** yourself"..
