Walgreens review: Pharmacy

My Physician prescribed a new medication for me on Aug 15. Today is Sept 12 -I have been trying to get this filled since then. It is nearly impossible to get anyone on the phone at the 3rd Ave San Mateo , CA location. I need them to fax a pre approval/ claim denial to my Dr so they can send the info to my insurance company. This is my 3rd attempt at calling the pharmacy- at the first day they just hung up. Now I just get put on hold - this time its been 56 min. I spoke with special medications of Walgreens but they said that my branch hasn’t filed online so they can’t help. Its a vicious cycle. I’m at a loss - help !
