Best medical supply store in Anderson, California (CA) 2024

It's been 48 hours since I went to the Dr. The walmart pharmacy still doesn't have the prescription ready. For some reason they are wanting to change the medication to something other than what i was prescribed and refuse to fill the prescription now. My dr office has been trying to contact them all day and they aren't answering their calls or returning messages. I've never had this problem with them before. ~Michelle
