Looks like this guy is very emotional.
1st: this kind of threatening is not a good business manner! Sorry to say that, but it is really bad attitude.
2nd: first deal, we made very clear that it is special offer and the terms was expired, the quotation for each terminals charging level was clearly defined.
3rd: How can they every time asked for such huge discount? Our price level is very reasonable.
Since they only threaten and never willing to talk. It is ok, they can do the media threatening, we have nothing to hide.
