VODACOM SERVICE!!!!!!

I would like to express my complete & utter dis-satisfaction with VODACOM as a whole. For one month I have been trying to sort out various issues regarding my account. All that happens is that I get transferred from pillar to post. NO-ONE is ever able to assist you. You cannot get hold of a single supervisor or manager. They are always in meetings & will call you back. Of course nobody ever calls back. I have not received one invoice for 9 months as my email address changed in July of last year. I have spoken to them month after month about this & every consultant you speak to says that have changed the details on their system. I too have told them more times than I can count that the ID no they have for me is the old bar coded ID no. This results in a problem every time they ask me security questions. Last year one of their consultants convinced me to downgrade my package as it would cost me less monthly. I was quoted a monthly fee for this. This has never happened & I am being charged more every month. Also my data seems to run out before the first week of every month which is impossible. I have spoken to the relevant department about this however this too has been ignored. I have been with Vodacom for 21 years & this is the service you can expect from them. THEY ARE AN ABSOLUTE DISGRACE & DO NOT CARE ABOUT THEIR CUSTOMERS. I DON'T CARE HOW MANY MILLIONS OF CLIENTS THEY HAVE, THIS IS NOT HOW YOU TREAT YOUR CLIENTS, ESPECIALLY AFTER 21 YEARS OF SERVICE.
