"terrible service"

My wife had an appointment in outpatients today, she arrived early for her appointment by 10 mins. After waiting for over an hour and a half (with our 12 week old son) a health care assistant came into the waiting room and announced that there is a 2 hour delay! I fully understand that the NHS is stretched to its limits and beyond at the minute due to government cut backs and the current environment we live in, but when my wife arrived and was clerked in for her appointment surley a member of staff could have mentioned that there was a delay. My wife had to leave without being seen to as she simply didn't have the time to sit and wait for two hours. This is unacceptable! If she had been told about the delay from the start she could have made arrangements for our son.
