Cannot get a hold of anyone to give me any help whatsoever.

I settled my vodacom account I was listed for last year and still vodacom has not updated my itc. I spent so much time with the customer care agents trying to resolve this while I have a paid up letter, yet need it from Vodacom, not their lawyers. Vodacom is not comming to the party and their call centre is taking me in circles. Can not get to speak to anyone to give me the letter or any answers whatsoever.
