If the reviewer(s) did not disclose their identity, it is already a sign they do not want to be pursued further about the paper under discussion.
My advice is to read again carefully their review and take their message literally: do a thorough review of the language/style in the writing of your study, the material is of good quality, but it is poorly communicated.
The reviewers are expert in the field, they may have interest in supporting and cooperating towards expansion of the scientific knowledge.
However, they clearly do not see a need to improve the scientific quality of your work, so they are unlikely to contribute.
If you nonetheless contact the editor, take into account that the editor may have good reasons to shield their pool of experts from authors interactions, at least but not at last to avoid undue influence (authors may be well known influential professors and reviewers may be temp postdoc on a thin line...).
