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

Find out the supervisors name, then put in writing via email or letter you wish to have this trial ended. I personally wouldn’t mention the telesales person. But I would make sure it was cancelled as it sounds like a never ending loop you will be locked into.

You tell us the name of the company and write a review of it someplace so others do not make the same mistake.

I’ll assume from what you wrote your wife did not click on anything she shouldn’t and you are not subscribed or paying this service.

We don’t know for sure he is trying to be deceptive. These people usually just read instructions to take you through the steps to do what you want. He answered your wife’s question honestly in the end. He might be stupid more than anything. If you live in North America and there is a possibility English was a second langauge for the person, I would make sure I speak to a supervisor in North America, see what their reaction is. If you are motivated write a letter explaining why you are inclined to not sign up for their services, because now you do not trust the level of service they will provide ongoing.

Also, what @LuckyGuy said.

Let it go.
