service paid but no delivery

On the 7th of October, i purchased bikini via online shopping of bid or buy it. According to the seller the goods were shipped using Aramex Courier service which i needed those bikini for my December vacation. I contacted the seller and she told me the good were delivered and i did tracked it on Aramex service and also called the keep promising to delivery after two days and i even gave them my direct cell phone numbers but still no delivery. My last call with Aramex was on the 08.01.16 15:54 which they promised to deliver monday the 11th January 2016 but still no delivery. i am so dissapointed in Aramex services and yes they ruined my perfect beach holiday without my hot bikini.
