Credit still not reflecting after 4 months

Seriously Vodacom. It has been 4 months since you were to credit my account due to wrongful billing on your side.<br> I have phoned your call centre about 7 times now, and they said it was an error made on your side and that it has affected more than 50% of your clients. They also said that a bulk credit will be done to reverse all the incorrect billing. 4 months later and the credit still has to be done, and I constantly get phone calls from your automated system telling me my account is in arrears. Bull! At the end is a link to the original complaint. Will someone competent please just get the credit done as this is starting to reflect badly on my credit score and I WILL NOT pay for an error that you made. I would really like to stay with Vodacom, but if you cant stop the inconvenience you are constantly causing me Ill have to go somewhere else.<br> <br> <br> http://hellopeter.com/vodacom/complaints/outstanding-query-3-weeks-***
