No Response to Hellopeter Report or Three Emails

I wrote a report on Hellopeter on 18 May but I have not received any response from you, although I see you have been replying to all the people who posted their reports days after mine. I also have not received a reply from the emails I sent to three different customer services emails. The first email was sent on 8 May and the other two on 14 May. My envelope containing important documents for the sale of my property was posted from Dublin, Ireland on 17 April (RL 543 693 501 IE) but it only arrived at JIMC on 21 May and all I want is the local tracking number! This is extremely urgent!
