Just had a call from my pharmacist and they have been assured that there is a delivery expected in 15 days to the wholesaler (I am assuming someone has contacted Mercury Pharma). They have marked my prescription as urgent and have promised to call to let me know.
I am in the process of writing an email to NHS England as apparently they will investigate and give answers (well that will be a first). firstname.lastname@example.org It is to do with it being a NHS prescription and the problems with filling it. The lady says they will answer every question on the email
