No communication!!!!

This is VERY irritating because I changed my account details from which my debit order supposed to go off and the guy informed me that he had placed me onto their \New systems\" and that all is on order however I kept on receiving calls informing me that my account was in arrears. I called in again and the matter was resolved as the lady informed me that vodacom was experiencing technical difficulties. She had assured me that the matter was resolved however, a day later the calls began again informing me once again that the account is in arrears. When I called again the lady that assisted me that the account is in arrears. Now my question is this... HOW DOES MY ACCOUNT GO FROM BEING ALL CLEAR TO BEING IN ARREARS IN ONE WEEK????<br> This is most irritating because I have to query an issue with VODACOM every month. At this rate I should have shares in Vodacom by now!!! "
