"Terrible communication in Ultrasound department"

The first time I went for an ultrasound, I was not kept informed about how long I would be waiting, and then what had happened to the photos I bought and whether they needed to run further tests or not after my appointment - we had to wait about an hour afterwards for the sonographer to reappear and tell the receptionist the answer to these questions. The reception staff booked my second appointment as I stood at the desk but didn't ask me if the dates and times were convenient for me, and refused to change them to a more convenient date when I asked them to change them. The second time I attended the ultrasound department, the reception staff told me that my appointment had been moved to the next day, but nobody had informed me in advance and they hadn't tried to contact me by phone or letter! They've had 3 weeks since the appointment was booked in which to try to contact me. I told them I was unhappy about this as my partner had taken holiday time off from work to attend with me and neither of us might be able to get time off for the new appointment at such short notice, but the staff didn't care and said they couldn't slot me in on the day despite the mess up on their part, and said that it wasn't their fault and I should blame the antenatal department (even though it's the ultrasound department who pick the appointment times and send out appointment letters!), and that I should have phoned to check that my appointment was still booked! This wasted four hours of our time, the petrol costs and car parking charges at the hospital. As an aside, both times the waiting room tables and chairs have been strewn with dirty disposable cups, food packaging, dirty tissues etc - think someone needs to clean up a bit more often or make more bins available!
