Netwerk24 app problems

We have been struggling for months to have an issue on my profile sorted out. Even though the profile is paid up to date and we have been assured of this fact multiple times by their call center, we get the same error that our account has been suspended, or there is a problem with the profile due to outstanding payment. This prohibits us from accessing articles and therefore using the app to its full potential.

The last time we complained - and they went through several procedures of logging on and off again and again - the call center advised that they will escalate it to their development team and I can expect feedback by the end of that week.

It is several weeks later and the problem is still persisting, without any feedback from a responsible person in their development team
