Call Centre + Bot not helping

Call Centre is useless.

i recently lost my phone. I need to claim from insurance - but there is no way for me to blacklist my number. You call the line and then they want to put you through to the bot!!!! - the bot is not helping!!!

This is a stupid problem to have!!! but its a problem all the same!!!

Thier website only has support for people that are on contract since they can log in and have options avialable... but us on pre-paid have no one except the bot to help us with the most basic of tasks!!!! Common!!!!
