you can ask them to cancel ahead of time and get a refund as long as you explain it's because the lost of trust and the fact that they don't provide the service they advertise. I did it yesterday and I encourage everyone to do it. Even if they stop, the refunds send a STRONG message to management. Also don't be shy to chargeback if your CC company allows you to. Companies like LastPass need to be made an example of, and you have the power in this situation.
