myh/familylink review: unauthorised charge 1

I have been checking through my bank statement and see that on 11th July a deduction of £90 was made from my current account with this reference. I did not make such a payment myself and have no idea how this amount could have been deducted from my account. This is clearly an illegal payment and I wish to have this amount refunded to my account.
