Great customer service
I signed up for a subscription when I really only needed to use it for one day. I canceled the subscription but it must not have gone through because I was later charged after a month. I canceled again and contacted customer service. They said the first cancellation must not have gone through but then refunded my money. That is why I will definitely use them again in the future.
