Appalling service and no management accountability. Incorrect billing to customers. ************ business practices.

I had a contract with Vodacom. Had been their customer for more than 25 years. More than a year ago, one of their consultant called me to check if I was upgrading since my contract expired. I queried that they debited my account and I had forgotten to check. She verified that the contract expired and promised to send my request to the cancelling dept. She said I will get an email. When I didn't get an email, I called Vodacom and another consultant informed me my contract was not cancelled. I requested to speak to the manager to no avail. I received a bill with zero balance, then two different balance owing. I have been to 2 Vodacom branches, one of them regional office in East London. In East London they give me contact numbers of cancellation dept in George western Cape. I spoke to the manager called Salome, I literally called her every week for more than 4 months trying to resolve this ******** bill. I have emails to back me up, they all gave me the running around. I asked Salome to give me ombudsman contact number as I never received copy of my contract. She promised to resolve my query, they have now handed me to their legal debtor collectors. They too I tried to explain my situation, they requested the emails which I forwarded to them. I received no response except threatening SMS and emails. This is affecting my credit score.
