No Feedback on communication

I have placed and order for goods, and was send an email to say the courier was unable to get hold of me. I have responded to advise on the times available for delivery and to date no delivery made. I have done another follow up on the mail received and asked when my stuff will be delivered just to no response again. I phoned today and was transferred to the courier without even notifying me just being transferred whereby he confirmed the number being incorrect on the order, of which the mistake was on my side however after two mails no responses it could have being sorted out sooner.
