I wish you luck with your endeavours.
For me they are completely arrogant and this may be because I am on the other side of the world. I don't hold out much hope especially as they can't even acknowledge any of my communications. But I will tell the world to avoid them.
As I said I don't think they have any customer service personnel and if they do they are certainly in the wrong job. Maybe all of this is being happening because of pitiful management practices led from the top.
