Poor customer service and no help with water metre issue

Ive been trying to put in the water metre token number on the water prepaid metre only to find out The metre number on the pad and on the card are not the same . Which means money down the drain and I won’t be receiving water .I’ve tried to contact the call center and the contact the WhatsApp number with no help im utterly disappointed with the customer service , it’s pathetic. I’ve never been so frustrated in my life .
