The worst company I have ever seen

Worst customer service ever nothing ever gets fixed tickets never get answered no correspondence locking of numbers that you port in on your own device they stop your cellular services their device they burn your cellular services. You have to purchase more. They get upset if you email the investigation that the representatives never answered back somebody always wants to get in your accountant. Some of the worst customer service I have ever seen

Garbage webview app

Every time I change focus to a different app and come back, the app starts over from the beginning. It’s maddening. Trying to use 1Password to manage my login information and every time I switch to 1Password and back, it starts over completely fresh like I’ve never opened before. It has all of the downsides of a website and all the downside of using an app.
