"Lost referral more than once"

My GP sent a referral to the Royal London hospital's antenatal care when I was at 10 weeks.   I was told to call the hospital in a week to check for the appointment.   When I called, the antenatal care administration said that they could not find my referral, despite a delivery note that had been sent to my GP. I had to call my GP to send another referral.  

I called again the next day, and the hospital administration could not find referral again.   I had to go my GP's office, pick up the referral, and personally take it over to the reception of the antenatal ward.    

At the hospital, there was a bit of confusion about my appointment.   At first, a new appointment was going to be booked.   Later, it turned out that an appointment had already been made for me, so I took the original appointment.   My address  on the letter was incorrect, even though the GP has my correct address.     I am concerned that the hospital is disorganised and will lose my files/data.
