Vodacom

I had to wait 2 weeks for my number to be ported from telkom to vodacom. After eventually getting my contract from vodacom on my previous number I noticed my old simcard is still active after people told me when they call me the call goes to voice mail. I contacted telkom who said I never app**** for the number to be ported. I called the consultant who helped me at vodacom, apparently its my fault because I switched the new phone on before the old simcard was deactivated(when no one told me to do otherwise). The matter has now been "escilated". Still waiting for feedback after more than a week. I'm missing calls, I can't do internet banking because im not receiving OTP's on my new phone. No one is taking reponsibility or actively trying to fix the problem, I am sent from pillar to post to try and fix it myself.
