Keep written records of this
Then if not settled you can contact the complaints resolution team in the office handling your case – contact details should be on any CMS letter you receive.
If not satisfied with this you can ask for a review of your complaint – called complaints stage 2 which goes to a senior CMS official. Contact details from the dispute resolution team.
At each stage a complaint should be acknowledged within 2 days and resolved within 15 days unless you are notified that it is taking longer.
If not satisfied with this process, contact the Independent Case Examiner https://www.gov.uk/government/organisations/independent-case-examiner

There is information about this at https://www.gov.uk/child-maintenance-service/complaints-and-appeals
At any stage you can also contact your MP (not MSP) which may help to speed things up.
