Dawn Wing - Horrible courrier

This is a horrible courier service. I had 2 packages sent from London. The first I tracked on Dawn Wings site, I noticed it was stuck in customs, so I called Dawn Wing and they told me they didn't have my email which was ******* as it was on the package. I gave the lady my details and continued to wait. I eventually called again and was told Dawn Wing was no longer clearing my package it was a company called Aramex. I had to then contact Aramex to get my package. The second package I ordered showed up on Aramex's site. But after seeing it in customs for about 2 weeks I called Aramex, and they told me Dawn Wing was clearing it. Nikki Hattingh from Dawn Wing told me they sent me an invoice to me on the 8th of jan which is a lie as on the invoice she subsequently sent me I could see the email was to a UK address. I immediately paid for the package on 21 Jan, and since i heard nothing back I emailed Nikki on tuesday asking when the package would be delivered. She did not respond. I then emailed her again stating that I had not received the package. She rep**** to me the next day at 8:00am (24 Jan) stating she had not received my email (even though my email clearly shows it was sent to her). She promised to get back to me. I did not receive a response from her as yet. This is terrible customer service.
