Their fault my problem

I ordered a iPhone 6 from fnb, first of all the phone was 2 days late and the wrong colour was delivered. The day I called to follow up on the delivery the colleague was rude and only advised me that I will have no choice but to return my phone to the driver, after a 10 minute argument. She advised me to call fnb to arrange and exchange.This was an incorrect process. I was transferred all over the place, I was advised to contact a department who advised me to contact other departments, Shane Rynor advised me to do the exchange at the istore! Istore will not exchange a phone that's from fnb's stock, I went to dot fnb who advised me I could have exchanged the phone with them with In 7 days For a silver iPhone. Shane refuses to take responsibility or to do the exchange, I was pushed from every department in the fnb contact centre, digital planet, istore and the device guru's, all I can to is exchange the phone for the same phone! I have spent so much money on waiting for the late delivery, calls and traveling and still I'm not getting anywhere! They refuse to do the exchange !
