If you still use WhatsApp, be aware-
1. You can be banned at anytime, for unknown reasons.
2. Your backups might fail to restore when you change your device.
So, avoid stories that touch-
Export ur most important chats.
Save them as text files.
Download other messaging apps.
Inform ur most important contacts of a porting schedule.
- The above is meant to save you from headaches and embarrassment.
...
NB-
I've tried several times to communicate the app's lapses to the company-
On Twitter, Facebook and by email.
They were all ignored.
The current run on the app will likely continue.

Good luck
