Hospital appointment

Please can someone help me, I went to the doctors in Armenine and was told I need to have an ungent X-ray at Mojon hospital, the doctor said reception will make the appointment, but at reception the woman said manana and wrote 012 on the form, she asked if my phone number was correct, I thought they must text appointments to you or phone, that was on Wednesday and I have another appointment to go back to see the doctor on Tuesday. This is my first time at the doctors since we registered a few years ago so I do not know how the system works. I know the number 012 is for making appointments online with your doctor but should I have phoned to make the hospital appointment. Thank you in advance for your help.
