How about instead of making demands and/or shoving papers in their face you have a discussion with them and ask for the reasoning why they're only giving you 50 test strips? Crazy thought, maybe there's a specific reason why they're only giving you that many.
When I was first diagnosed, I was given one Levemir pen, 50 test strips, and told to schedule a follow-up appointment the next week. During that time, my doctor was analyzing my c-peptide and GAD antibody tests to confirm the correct diagnosis.
Long story short, the following week I was prescribed bolus insulin, 250 test strips a month, and a Dexcom CGM (I'm in the USA).
Point being: have a conversation with your doctor to explain your concerns. If they're still giving you a hard time about it and won't give you a solid explanation THEN you can resort to the methods other people mentioned.
