Fix this before I take legal action

This is my third attempt to get service from Aramex.<br> <br> You incorrectly entered a bar code onto your system that shows you delivered my goods on 4th April when infact you have delivered nothing. waybill ***.<br> Because of this error I am unable to claim a refund from Amazon as they assume the goods have been delivered. I have advised you of this but you have done nothing. Hence, I give you 48 hours to do the following: Advise Amazon of your mistake so I can claim my refund of $215 or else you are legally liable for that amount as it is your error that is hindering me from claiming my refund. Amazon will decline a refund after all these weeks. So you better hurry as May is my 3rd month without delivery of my goods. Not acceptable. I want my refund or else.
