Why have I been charged in full for premuim

Chelcie • 28. Mum to 2 girls 🫶🏼 UK

I’ve been charged a full yearly rate for a subscription when It said £2 something a month?

I am only trialling this premium account and I have been charged £28 any help?????

Not happy as I’m on maternity leave and now I’ve been left in my overdraft for the next 2 weeks 🧐
