More frustrated than ever with vodacom

So after my review, I received another call from vodacom. I'm even more frustrated than ever. I'm trying to explain to the consultant to please investigate my matter that has dragged on for months and EVERY TIME I CALL I GET TOLD A DIFFERENT STORY AND THEY ALL SAY THAT THEY CAN'T ANSWER WHY THE PREVIOUS CONSULTANTS ADVISED ME SUCH!

Your consultant all did not listen to me. Everyone telling me different stories and telling me that they cannot answer wat the previous consultants were telling me but you all use the same system. It's frustrating
