Worst customer service, my Dr. has faxed in my Rxs and they have lost them. The supervisors nor customer svc are not willing to do a search by fax # to check for the Rx if is still in the que waiting to be process, it's very frustrating dealing with incompetent people hired to do a job a simple customer request.
