TLG Autovantage Charged me when I did not sign up Trumbull Connecticut

I believe this company may be an offshoot of a travel company through Budget Car Rental - a sort of discount offer for travel plans. I tried it once, years ago, and cancelled it, due to a clear campaign to confuse consumers - they offered gas coupons, but then sent confusing checks, that when cashed, signed you up for new subscriptions. They recently charged my credit card a year's subscription. I called to cancel, which they did, but did not credit me the full amount. I called again, and they said they had "pro-rated" the credit. I demanded they credit the full amount, and while they agreed to, I assume I will see more shenanigans from them. Doing a google search showed many many complaints against this company.
