The response from your MP will be that the minister cannot act, You have a right to fight this. Tell them about your circumstances and ring repeatedly until you get the result you want.

No, the rules changed in 2002, but they didn't inform people who used to have blanket exemption before that point. In 2002, the info wasn't available online, so they'd have had to write speculatively to DH to ask if an irrational rule change had occurred. Diagnosis before 2002 would mean they didn't get reminder letters either. Finally, it's illegal for them to raise a charge if the individual didn't knowingly deceive the NHS. Section 122 of the Health Act 1999, or 194 of the NHS Act 2006 (same wording). Stop defending an indefensible, illegal act and stand beside your fellow diabetics. It is depressing that you acquiesced so quickly to this unfair victimisation of other people. Are you really that much of a pushover?
If anyone would like to know how to get around it, simply point out that the pharmacist never asked you for your certificate. My charge was waived as a misunderstanding and I'll now fight for a blanket exemption, such as is enjoyed by those under 16 and over 60. Easily administered in those cases, as it should be in the case of incurable conditions.
this people should be trained or told of changes.
