Easton-Berry refuses to send me a paid up letter

I paid up my account, and after numerous emails, I still have not receive a paid up letter. Why should I have to resort to Hello Peter to get a basic thing done? I however received the full amount that I had to pay within 24 hours with the request to urgently make payment arrangements, How is it possible for them to answer that email so quickly, and simply ignore my other emails? Selective reading is what is happening at Easton-Berry Collections. This is unacceptable!
