MTN has made it impossible for me to port away

<p>When I ported to MTN in November 2016 i could not receive smses from some vodacom numbers. I have raised several complaint to MTN without any resolve of the issue. The great irony is that to port back to Vodacom I need to receive a port authority sms. And guess what, it sent from one of the numbers that I cant receive smses from. So I am literally stuck with MTN. </p>
