Psi Natural Health review: Money taken out of my bank £28.47 without purchase,

I have not purchased anything from this company so looked up the company on Google and saw comments of it being a scam. £28.47 was taken out of my bank account 2 days ago but I have never heard of them before. I don’t know how they got my bank details. I do not have an order number for this company as I didn’t order from them so I have no further information
