Wife’s Etsy store closed down

My wife created a new Etsy store to sell home made children’s activity books. Shortly after creation, Etsy closed it down without explanation, banned her from creating a new store, and when she appealed they sent a seemingly automated refusal within minutes. What can she do now to resolve this? The only issue she can think of is there was a £2.39 fee owing relating to the set up. It was in red suggesting it was unpaid, but she had paid a different fee and they had her credit card and bank details.

Were they 'AI' created books?

I've never been able to find a phone number for Etsy.

Would it be worthwhile contacting them via message on Facebook or twitter and that might get a better response.
