Editors refuse to link an original article to a reply

A few months ago I wrote a reply to an article that has been published in the Breast. The original authors performed a meta-analysis without a proper search (they only searched PubMed, with very limited keywords, and instead included articles that did not meat the inclusion criteria).

Our reply was published in print before the original article. However, the original article was published with no mention of our reply, nor did the authors respond to our findings.

What followed were numerous e-mails to the editors and journal managers of the journal, to this date with no effect. They keep saying they cannot add a link to our reply to the original article as it has already been published. However, our article was published in print half a year before the original, so they must have had enough time to sort this out.

Replies are always written after the publication of the original article, how else could on opinion be formed? The original article should always be linked to the known replies, and published replies should always be answered by the original authors.

Or am I wrong?
