Mtn -Phone Black Listing

<p>I lost my phone a week ago, I have been trying to get it blacklisted but i keep being told the same thing over and over again that they have a technical problem and they cant blacklist phone. How is it posssible reali for a technial problem to last this long, Should i realy have take more than a weeks to blacklist my ****** phone. This is realy unprofessional . Why do you even hire technicians if your systems never work .</p>
