EXTREMELY BAD SERVICE FROM VODACOM, NOW NO SERVICE.

I have a contract phone with Vodacom. I have no service and have phoned them. I now have no connectivity and spent over an hour on a Telkom landline with a message of high call volumes. If they give better service they would not have "high call volumes". My issue was supposedly escalated yesterday, however, still no service. I work when Vodacom shops are open, so that is not an option right now. How do I get this resolved. I have encountered rudeness and the call is dropped before I can rate the service. I have been sent the 4 questions and answered them saying how poor the service is. Still nothing. Every month they happily take payment but service is just terrible. I had a query which continued until after my two year contract automatically rolled over so I am stuck with them for another two years since late last year. I have several phones on the Vodacom network, RICA'd in my name. I am seriously considering removing what I can. Does anyone have suggestions on how I can get out of this contract which is older than two years and just rolled over automatically? I need to do online banking, it is month end. With no service, no OTP's and no banking.
