How to escalate a complaint about errors produced by a journal from the Nature publishing group when Editor doesn't respond We have a scientific paper that was published at the beginning of this year in "Scientific Reports", an open-access journal by the Nature publishing group. However, upon publication, as authors we were shocked to see some of the figures (which were uploaded to the journal's website during submission) altered in an unacceptable way that changes the scientific meaning of the paper. It was clearly a "production" error during the final processing of the manuscript by the publishing team. 

We have since been complaining to the journal and its Chief Editor (for several months now), but without any meaningful response from them; the Editor never bothered replying and another assistant promised to fix the errors but nothing happened. 

As authors we are very frustrated to see our work being distorted online (in front of the readership) and we don't know how to complain about such negative experience and get the errors fixed.  Any advice on who to complain to or who can escalate this seriously with the editor/team of this journal would be appreciated?

Release a technical report which doesn't contain these mistakes and explain in the report that the errors were made by the publishing team. 


  we don't know how to...get the errors fixed. 


It seems you have exhausted the usual, informal routes. Perhaps you can escalate with your university's legal team, since there's surely a breach of contract which reflects badly upon the university. A strongly worded legal letter will hopefully prompt action.
