"Prescription delay"

I visited Neurology at the end of March 2015 and the assessment was thorough and on-time. The issue I have is with the time it has taken for a much-needed prescription. I waited three weeks before contacting my GP who was supposed to have been faxed with my prescription and advice for me to see a specialist. They had received nothing. I then contacted neurology who said they were waiting for a consultants signature and that it would be done that day. Not sure why it took three weeks for a signature, sounded an awful lot like it had been forgotten about. My GP hasn't received the fax a week later despite them contacting neurology on my behalf and being promised for the second time that they would sign that day. Completely inefficient administration.
