Cannot blacklist a ****** phone

Two contract devices were ****** out my bag on. I tried to call mtn to blacklist and pick the phones. I have been shunted from pillar to post and almost a week later I still havent had any confirmation of the request. When I was in the police station they were even able to witness how pathetic their processes are. I will definitely not be upgrading with them ever again. Customer service is appalling and the business division process needs to be reviewed. We live in a society where we get to ****** after hours too and should be assisted after hours with blocking and blacklisting phones immediately
