Hi! New here myself!
I don't blame you for being miffed! I would say there is something definitely lacking with the medical care on offer in your area, especially if you are not getting the help you want from either your own GP, or your hospital and Diabetes Nurse.
Without sounding too political, it's a problem that we are all going to face to a certain degree once the new government measures are brought in to reform parts of the NHS. I've found myself that here in Bedfordshire, our own GP surgery has been nigh on useless when it has come to changing prescriptions. There is a breakdown between the service between our hospital, where my little boy's Paediatric Diabetes Nurse is based, and out own GP. He was diagnosed just before Easter this year (about 2 weeks after his 9th birthday

) and I had several arguments myself with the GP about test strips. She wanted to know why we were testing so much, that one box of 100 was only lasting us about 8-10 days! Since he was newly diagnosed, and we were still getting a handle on what to do, not to mention the shock - I was more than a little cross with her, when she suggested we used less, because they cost £35 a box!!! Needless to say, I contacted our PDN, and she got onto them straight away, and that issue was resolved. There's more, but I'll leave that for another day!
Bottom line, I'd try an official complaint. What have you got to lose? If they don't get feedback on services, good or bad, then nothing can change, but if enough people make noise, it cannot be ignored.
