Fixing what isn't broken. The app is only available in German (you could use your browser's translate feature on the site). I thought I'd at least benefit from the data amount-tracking widget placed on my home screen, but it doesn't automatically update and requires you to enter the app and pull down to refresh..
Thanks a lot for your feedback. Greetings, Jonathan

The app does what its supposed to do.. they should add a version of the app to the microsoft store to give people easy acess on PC.. since managing your bills on your phone is sometimes a real hassle especially with elderly people

Here is my experience with Congstar: I signed a contract with a dealer and was doubly deceived regarding the GB amount and the cancellation options. After installing the app, I received a fraudulent SMS asking me to enter my bank details. Since the message was in yellow, I thought it was related to Congstar, but it was a scam. Customer support didn't want to help and seems to support deceitful dealers. Stick with a reputable company, as Congstar is only after quick money.

I'm sorry you had a bad experience. The text message sounds like phishing and certainly didn't originally come from congstar. Please get in touch so that we can check which dealer your contract was concluded with.
