CVS review: Prescription delivery or pickup

For past week have bee trying on website for cvs to get prescription delivered, then I get robo call pres ready for pickup, go on site, try again. Unable to pickup prescr myself because they allow delivery trailers to park in the three handicapped spots-constantly, police have been contacted. Parking lot is not safe for disabled person with mobility issues. Pres is for heart med, have heart surgery scheduled for Tuesday at St Eliz. Called pharmacy, treated ridiculously rudely and was hung up on. I am documenting this info various places in case the week delay causes any problems, I still have no clue about my prescription, is it being delivered, how to avoid this ongoing thing in the future, hope no need for lawyer
