No Joy on Vitality and Miles linked to bank / rewards / fuel

I am looking for help with vitality drive and money.

My fuel cash back is not reflecting. My healthy food is not reflecting.

I want to change my healthy food to Checkers, but cannot find where to link our reward numbers.

I cannot find an email to send this to. There is a whatsapp chat bot that is not helpfull.

Please can a human contact me on *** and assist.

Regards,

Nico.
