"Bloodtest Department"

I have been trying to arrange an appointment for a bloodtest from yesterday evening and again since 9:00am this morning. The recorded message is the same of high volume of calls and all agents are currently busy. I am currently on my 3rd try of today and still on hold for now 20mins. This clearly outlines that this system is failing and that this needs to be reviewed on how to improve this service. If this means investing in a new system or even to employ more staff then it needs to be done. It has now been 30mins on hold for this service and I am clearly not about to get through to the department and decided its time to give up. My thoughts going out on to the elder that have to suffer in this waiting. I look forward to hearing the reply to this above review for this has been the worst service experienced so far.
