2 issues: 1. I was charged for a membership fee even though Ive removed my credit card from MeetUp. Its been saved somewhere and is unlawfully being used. Therefore, my credit card needs to be removed in the backend. 2. I was charged for a membership on an account that Im not active in and didnt have membership charges when I started. Therefore, the charge needs to be reversed. User's recommendation: Check to ensure your credit card, even after you remove it from your account, isn’t stored and being used.
