Telkom Mobile Upgrade nightmare

I have tried to do an "early upgrade" (where you pay the difference of the remaining contract) for the last two weeks now that I even went in store and everything was fine until they had to issue my new phone, then they say the system has blocked me due to incorrect answers on questions asked. I went through this exact same issue 2 years ago and it has risen again. I waited for an hour and a half to get to the front of line, spent another 20min to do the upgrade and that is what I get. The consultant logged a Credit Vetting Issue, which is 3 days old already and has not received attention. I am seriously considering removing all my contracts from telkom as this seems to be a constant problem.
