Wertgarantie is the insurance policy you agreed to for your mobile phone, your television, laptop computer, PC or other kind of apparatus. If you wish to end this insurance policy, then you must yourself contact Wertgarantie, not us. If your mobile telephone contract has run out or your mobile telephone is no longer in your possession (broken, sold on) you still need to cancel the insurance policy. Your mobile telephone contract is with one or other mobile telephone provider and they have nothing to do with the insurance at all.
