Telkom not backlisting a ****** phone on their network

I have requested that my phone gets black listed by Telkom but seems to be unwilling to do their work

My car got broken in to on 04/09/2020 i went to saps the following morning to get a Case number

i have now called Telkom more than 5 times over a span of 2 Weeks to have my ****** phone blacklisted, every time i phone i get the "please wait 2-5 hours for your ITC number""

@TELKOM please advise why you are not willing to assist

My insurance company now refused to submit my claim due to your incompetence
