"Scanning department issues and disrespectful staff"

Today I feel ashamed of the organisation I once felt proud to work for. I witnessed insensitive, disrespectful and possible dishonest practices within the NHS. My husband was due a cancer staging scan today, when we received a call asking him to get down to the department immediately for his scan on a "first come first served basis". When I informed them that he wasn't due for three hours and would not have fasted sufficiently, we were told the scan was cancelled. We were given conflicting reasons that they had run out of injections, manufacturing difficulties and quality control issues. As they are unable to reschedule for 8 days, this means his other scans have to be rescheduled for after and subsequent cancer treatment will be delayed for 1-2 weeks, Whilst I appreciate staff are under immense pressure, when I mentioned the delay and cancelling the other scans, I was told very unprofessionally that I was wrong, that he wasn't the only patient with cancer, it wasn't her fault and was sick of being shouted at by everyone before disconnecting the call, Thankfully the MacMillan nurse is trying to reschedule the other scans, but this unprofessional and disrespectful attitude has caused avoidable stress and anxiety.
