Cam v4 Cam plus problem

I have a Cam v4 and it came with one month free Cam plus I am still in the one monthe free cam plus and charged for extra one month cam plus even though I never added cam plus after the free month my credit charged WITHOUT my approval, YES I did contacted customer service they couldn’t figure why I got charged and couldn’t credit me the charge that I never approved all they were able to do is cancel my membership to cam plus, so please be careful when dealing with cam plus membership, also I was NOT able to remove my credit card info from my account after what happened.
