Exceptionally bad service!

I am now taking to social media as no one at Paxi can assist me with information!!! I send a parcel on 27 May (5-7 day option) - it is 7 July! I have been phoning almost every day to see what has happened to my parcel. No one seems to know! How can this be??? This might be the most affordable courier service but their service is exceptionally bad. Especially if you try and track your parcel! What really got me was that the one contact center agent told me to go to the store and try and get answers!!! UNEXCEPTABLE!
