"Delay in appointment at outpatients and DIY advice"

Seen at the Liver clinic beginning of October following abdominal screening (history of breast cancer) advised by letter would be reviewed in clinic 3 to 4 months. No appointment received and contacted secretary to be told no appointments left for February - next availability would be sometime in March and that I would have to ring appointments myself. Surely this should have been picked up by the Secretariat following my last visit?
