Cancelling a subscription can be an intimidating and anxiety creating experience. NOT WITH THESE PEOPLE!!! Today I logged in to my account. ***** linked in as my Chat contact and in less then 1 minute the subscription was taken care of for me!!!! I have had to fight too many providers about cancelling subscriptions so THIS WAS REFRESHING!!! Such a contrast and it makes me want to stay connected with them if I ever need their services again.Don't hesitate to access their services and products.

What do you like best? The support solved my problem really fast. Amazing. What do you dislike? It's quite expensive for an annual subscription. Is there any monthly option? Recommendations to others considering the product: It's really useful. Try it! What problems are you solving with the product? What benefits have you realized? They cancel my subscription even it has been charged. And the benefit was my CC transaction was voided. Amazing.
