Can't see her name on the ASA website (can bruv's though!) if someone has raised a complaint then a reference number would have been issued. Time to risk my burner and pose the question, will she pull up the portcullis and block me or offer an explanation? below is my comments to her I've even used Bruv's reference number!
When a report is made to the Advertising Standards Agency you should have been supplied with a Complaint reference number for example A25-1297374 . If you link your own reference number this should dissuade any further queries or issues with your income claims.
Luckily their skepticism has given you an advantage to display your last 2 years sales figures.
Fortunately in the UK all incorporated companies (including private and public entities) are
legally required to submit their annual accounts to Companies House.
These documents are part of the public domain and can be searched, downloaded, and viewed at no cost.
Searching your name on Companies House should have given them the information they need.
