ACCOUNT STILL NOT SORTED OUT

Hi have not received a positive response with regard to my complaint about my enormous vodacom account. I received an sms informing me that someone will come back to me but to date hereof no further response. i only received a further account informing me that over R3000.00 is now outstanding. i have never in my life been so upset with vodacom. if this is how they treat a customer that has been with them for years, i don't know. i have never once had a complaint. my account has always been paid on time. not one default but all of a sudden an account triple the amount. how can this be. i am very disappointed. i always tell the people that vodacom is the best service provider, but at this time i am feeling different. i will at this change to a different service provided without thinking. i can explain my dislike at this stage. i need something in writing to rectify this matter. i do not want to have my cellphone to be cut off as i do not get any help or response. where do vodacom think people must get money for enormous accounts.
