CONSULTANT REFUSES TO ASSIST RE BLACKLIST ISSUE & PUTS PHONE DOWN ON ME

I called Telkom Mobi (081180) this morning to blacklist my son's mobile phone (registered in my name) that was ****** last night. When I was asked my home address I was unable to recall where I was staying when I signed the contract as it was so long ago and I have moved since then. I explained this clearly to the consultant- Nodumiso Mguni - and I offered her 3 possible addresses, plus she had my full name and ID number. She refused to confirm any of the addresses - one of which was correct as it turns out),citing it was against their security protocols (which I do understand) but then she flatly refused to ask me the security questions that would have moved the process along. She also asked where my son gets billed and while I was asking him that question, I asked her to pls wait for me to get that info and she then terminated the call! Immediately thereafter an autogenerated voice came on asking me to rate the service and that didn't even work either as each time I pressed 0# to signify my problem was not solved, the voice kept repeating 'we notice you have not responded.' Next level horrible Telkom experience, yet again. Nodumiso, your behaviour was disgusting.
