Wow, surprise! you are really good at interpreting out of context！

Ok, just let me tell the truth: this customer’s slash was somehow broken when using the auto pumping function mistakenly(ps, i still have the pics he sent to me) , and we were sorry about this, cuz there is no very detailed instructions for this, still, he did not ask how to use it, so after asking my leader, and i was told that we can send him a new one if he pays $500, the original price is $3499,and  this customer had also agreed at last and asked me for invoice etc,(see pics attached). one big mistake i had made is that we have sent the machine before he paid us, 15 days passed, we still did not receive the $500, and i tried to contact him several time, cuz i was just a gruduate, if he was not gonna pay it, it would be me who pay for him, still no reply!

is this a normal person who let an intern just graduated paid for him? so we just stopped his after sales service；also i was blackmailed if we dont provide support, he will see something bad on the forum, we think most of you guys will be reasonable and will understand~~~

Thank you for your surprisingly quick response. Now you know American consumer is not as stupid as you thought especially in this Hightech industry. 

You said you are sorry, you said you will send a new machine. Look at the DATE of Conversation. 

Now look at the conversation and you tell me who took the matter out of the context
