Wish taking money from account without my conscent

I was browsing on the Wish website at the beginning of Nov.I bought something from them online a previous time but it took 6 months to reach me.So i decided not to buy anything again.Then on between 7-11 Nov three different amounts was taken from my bank account without my permission.I would love to know what I actually bought,and who gave them permission to use my card number again.I want these transactions reversed ant the money back in my account please because i am sure this is not legal
