Ratings and reviews

In principle fine, you don't need to use it very often, but I'm disappointed with the last changes and the backoffice systems. Upgrading to a more expensive data connection was fast, but downgrading again: Now I'm charged for two different data contracts on the same phone making it twice as expensive, and I only followed the instructions. And yes I checked the validity period. First I was charged for new package and then old was extended instead of replaced at end of validity period

Follow up: to solve this I opted to have my account debited for top up the next day, the the top up monthly section. Once that went through, I terminated that option, then set the debit option so that once my credit gets to a certain value, it should be automatically topped up. Let's see how that works. I checked again to see if my original problem was fixed in the app and it wasn't. For the rest, I'm not going online; it's nonsense.

The app adds no value or better UI. It's basically a web view of the website.
