I need my medication

I will never use Pharmacy direct ever again. I have been trying to get my medication for weeks now. It was delivered however I only received half. I received a message indicating that my account was in arrears. I always pay my bills. When I checked my account it has a credit. I called, the consultant informed me that someone from the pharmacy will call me back. I am still waiting. In the meantime I don't have my medication which I require urgently.
