I don't feel like to give Chase farm hospital any star at all. All I wanted to do is to change an appointment but the switchboard was putting me true to different department, until some one hang up on.
If I don't notify them about changing appointment it's a problem because there won't be a next appointment. If you don't show up as well is a problem.
The switchboard attendants need to improvement.
The waiting time over the phone is ridiculous .......
