Blidz – A subscription I didn't authorize

My name is Sheryl Richardson Herman earlier this month my information was hacked and someone purchased this subscribe to this place and when I started getting the emails I replied back to them asking them to cancel this subscription and they told me no and the only way they would cancel it if I didn't authorize it and I replied back again and told them that my information was stolen and I haven't heard from them yet and that was 2 weeks ago
