So much for escalation!

I have been waiting for my parcel since the 17th of February! First of all I had to be the one to call and check why I had not received it and only then was I allocated someone to deal with it. I had to wait another week to get an invoice because the supplier under declared! I do not even know why these charges are imposed on me and not the supplier as I had not requested this, I presented all the necessary documentation required from me truthfully so. After having paid the ridiculous fee equivalent to my parcel, I am told I have to wait more days and that my case has been escalated. What is the turn around time for this and shouldn't the response be quicker after escalation? I am really not happy right now!!! I would like my parcel deliver ASAP
