"Poor Communications - Repeatedly got the phone…"

My son was due to attend for CT Scan today on his kidney as he has kidney stones. He started being sick a short while before he was due to attend, possibly due to the antibiotics he is on for a severe infection. So we thought it best if he didn't go as he has to take some liquid before hand and he would only sick that up. We tried ringing the phone number we were given, however all we kept on getting after about three minutes wait was the message "the other person has hung up". We tried repeatedly and also tried the main switchboard number and they put as through but we repeatedly got put back to the switchboard, who were very patient and re-tried to connect us without success.

The NHS makes a big thing about people not attending and the costs of this which I agree with, but when you try to make contact to explain the situation you can't get through. Perhaps the trust needs to provide an alternative communication method that doesn't need to be manned, such as an email or a mobile number that patients can text into in this sort of situation.
