Review Unprofessional

My baby was born on the 10th of Nov.
Dr Moodley was the pediatrician... so I phone the office to make 6week appointment. They close on the 18th and doesn't have space. All good... asked for appointment in Jan when they get back... so the lady tells me that she doesn't know when dr will be back in Jan... the office staff will be back on the 6th... I was told to phone back on the 7th or 8th... by then they should know when dr will return... WTF... how unprofessional is that...
