I caught a customer service rep pulling a devious trick, what should I do?

I have been using an online service on a free trial, and the service was ended early due to an error on the service provider’s side.

I’ve been trying to get it resolved, but my wife contacted them via web chat to see if she could help, maybe ‘sweet talk’ em or whatever. They didn’t help her, BUT something worse happened.

This chat person basically said “if you log into your husband’s account and click the subscription link, the service will be restored”. Bear in mind this was a free trial we were trying to get restored. THEN the guy says “just use the card info that’s stored in there”.

My wife’s a smart cookie and saw through the ruse, and said “So basically you are telling me to authorize a paid subscription on my husband’s card?” Answer from chat guy: “Yes”.
