Does anyone here had an experience with a late pack of documents from UK Embassy couriered by 2GO?

Got a text from VFS UK Visa last 31/05/2011 stating " Processed visa application ref no. xxxx will be endorsed to courier 2GO aboitiz on 31/05/2011. For Metro Manila delivery will be 24 to 48 hrs/ for Provincial delivery will be 48 to 72 hours." it has been 4 days now but until now I haven't got the documents. My excitement has turned to worries now. I called 2GO early afternoon and said they will track it for me and will call me back. But they haven't called back.
