Super fast response to billing issue. I had an issue with my subscription renewing when I had cancelled it. I worried because I know how this usually goes -- enjoy the next year of the subscription while we make sure it doesn't happen again. Nope: they got back to my email -- on a holiday weekend -- within 2 hours. They were ensuring that their cancellation system worked and immediately issued a refund. I don't know many places this good on something like this. I otherwise did enjoy the service while I had it.

Looks very promising in a competitive market. The product itself is visually appealing and at first glance is providing protection to users. The company also responded quickly to some feedback on just one error in their use of English.

Jumbo beta crash related diagnostics I have been a very loyal Jumbo beta tester for quite a while. I experienced instantaneous crashes last night on my iphone SE-2. The crashes continued despite my restarting my phone. It may have had something to do with my trying to activate 2FA with my LinkedIn account; but I couldn't be sure. I left an email to the Jumbo support team explaining my situation and asking for help. This morning, I received a very cogent and especially well-composed email from Isaac on their support team. It exactly spelled out the steps I ought to take to rectify the issues. I am most grateful for the excellent help. - Andrew A Roy

Great App, Great support I tried the service with the free trial offer. I must say, the app works great and serve a really nice purpose. Unfortunatly the price was a little too heavy for me, so I didn't want to go for a full subscription yet. But, as I'm a bit lightheaded I forgot to cancel my free trial before expiration. The support team was really nice and understanding, agreeing to refund my subscription quickly. Great App, Great Team

Jumbo always provides customer service… Jumbo always provides customer service above and beyond. They actually read input and noted from customers and respond appropriately. So happy with the protection for my cell phone as well! top notch company!
