ZERO CUSTOMER SERVICE !!!

I put a limit on our Vodacom account on the 08/05/2015 after we received a huge account. After receiving another huge account in Sept 2015 I contacted Vodacom again to find out what happened ????15/10/2015 was given a reference number and told I will be contacted in 24 hours, phoned again on 26/10/2015 after no hearing anything and got told systems are down they will phone me back. Phoned again today and was told systems are down they will phone me back. To my surprise I did get a call back to be told I did not follow the correct procedure and gave the incorrect info of what I wanted. I DO NOT WORK FOR VODACOM, I phoned in on the 08/05/2015 and did what I was told to do, I was told today they sent an e-mail to Michele who worked at our company 4 years ago. IF I AM NOT TOLD EXACTLY WHAT I NEED TO DO, HOW WOULD I KNOW ANY DIFFERENT. AS FAR AS I AM CONCERNED VODACOM HAS ****** MY COMPANIES MONEY. WHY SHOULD I AS THE CUSTOMER KEEP ON FOLLOWING UP ???
