Delink device DOES NOT WORK (web or app)

Delinking of devices does not work on app or web. Tried this for a couple of days still no joy. Call the Vitality call center and key in my ID number. Options on the prompt do not include existing Vitality member queries. So I pick Vitality activation and ask to be redirected to Vitality call center. They ask me again for my ID. I ask them for a direct line for the Vitality call center for existing customers and they still refer me to the stupid ...998877 number..SMH. I tell them the issue and they request screenshots which I have to send to the generic vitalityinfo email address where the turnaround will be 24-48 hours and they still have to forward this to some other team that will require proof that delink doesnt work. Whey would I call if this works. So call center staff cannot help regarding such issues. Equip your staff to help with such queries. I foresee a 2-3 days turnaround as this query will be forwarded to another technical team.
