Blacklist Your Phone - Not an easy process at Telkom

I have had the worst ever experience. I have been trying to blacklist my phone as it was ******. I was told that this process would be done within 2-4 hours, Its been more than 24 hours and nothing has still happened. I requested a e-mail address for me to follow this up, I was given a e-mail address ********** It appears that this e-mail address is not even working. The mails don't deliver. One cannot phone them as there is no number to phone. Absolutely shocking service. The consultant that helped me at the call centre's name was K****tso Ndamasa. If someone from telkom sees this. Please assist. Time of second report 15:00 10 October 2018. Check his e-mails sent to blacklist my phone.
