Looking for a new Ro

Hello! I am looking for suggestions for a company I can go through to get my prescription for Zepbound that is not Ro. Long story short they are trying to invoice me $249 after already paying $449 for my medicine two weeks ago (12mg). They are saying I am out of my 45 days window and despite showing them all the receipts showing I was they agreed I was in fact in my time frame and then told me they cannot do anything about it. Needless to say I am done with them. My doctor while amazing at everything else doesn’t believe in GLP-1s so that is a no go. I am looking for a new place that similar to a Ro where I can get my prescription for zepbound. Thank you so much for your help!
