Lifestyle legal ******* allegations

I'm very dissatisfied. I've never dealt or phone this business to help me with anything. Now all of a sudden they summon me to pay fees for something I never acknowledge to. They got hold of my banking details on a way and keep on deducting money from my account. They've never even phoned even to try to talk to me but they sending me letters they going to take me to court. I'm tired of them keep on threatening me. How can I get rid of these people
