New girl Tammy at pharmacy failed to call me back ...

New girl Tammy at pharmacy failed to call me back regarding insurance problems I was having getting an Rx filled. If she had called me to begin with or returned my calls in a timely fashion I could have fixed the issues sooner but because she never did my Rx is going to be 5-6 days late. She said she called my cell but I never got a call or a voicemail. I called multiple times and even requested that she communicate better as my Rx is a time sensitive issue. I tried confirming my number 3-4 times on the phone and in person. For some reason she ended up calling my work (I number I didn't give out), on my day off. All these problems could have been avoided if she called me back at the right number and left a voicemail on day 1.
