I rang at 4.40 today & I was told that I would be dealt with shortly. I was given the option of a call back in 27 seconds which i took but it never happened. I was on the phone holding for an hour waiting.I rang on another phone at 5 but I was told the office was closed but meanwhile on the other phone which I rang before 5 I was still being told my call would be answered shortly. The deadline for there special offer was for today but ironically you couldn't get through from 4:35...
