Laura messaged barneys bargains regarding Kate being gifted a free trip to the Christmas grotto
Ok so there's two issues here.
1. You contacted Business 1 (Barney's Bargains) to lodge a consumer complaint about their use of Business 2 (Kate Hayes Makeup) which should have remained confidential.
2. Of the 6 lawful basis' of sharing data, consent would be the most suitable, but none are applicable here meaning Business 1 have passed your data along illegally.

3. Kate Hayes Makeup as a business has then used data provided to them illegally and broadcasted it to however many thousand followers she has, again without any legal basis for doing so. As a business, she has basically stuck two fingers up to every principle included in the legislation,especially the confidentiality and integrity principle
https://ico.org.uk/for-organisation...iples/integrity-and-confidentiality-security/. You could argue that the aim of that post is to cause you danger or to encourage her followers to send you abuse or as the ICO would term it "risking your rights and freedoms."
4. Check the register , I bet neither of them are registered with the ICO which they might see as another aggravating factor
https://ico.org.uk/for-organisations/data-protection-fee/register/ .
I'd put all that in a complaint along with a copy of what you sent Barney's originally and screenshots from this twat outing you and send to the ICO, business 1 could have caused someone severe danger for making a calm professional complaint, and "influencers" really need to get a grip as well that if they want to operate as a business making money from the general public that feedback and sometimes complaints will be part and parcel of it

ETA: I'm sure KHM has a company on companies house? Send them the links to that as well. The ICO will like that as it will give them definitive names and addresses to send correspondence to.
