No assistance from Vodacom on *****

I am appalled at the service received by Vodacom who NOT ONLY has been incorrectly debiting my account for months but REFUSES to assist in trying to rectifying the situation. When I called their legal dept to resolve, was told to send through an affidavit & certified ID which confirms that I have NO accounts with Vodacom & they have incorrectly debiting my account. I sent this through the same day, 16 Oct. On 19 October I had not received a response so I called the legal dept and they stated they had not received the mail, I need to wait and call back on Wednesday. I resent them the mail on 19 October and did not receive a response. I then called on 21 October & was told they had still not received the mail & i need to wait until they receive it. I then resent the documents from my work email. I still did not receive a response. I have been successfully sending & receiving mails on both email addresses. On 20 October I call them again & they have not recieved any mails from me. I then asked to speak to the manager/ supervisor. Intabeseng Mokhandi assured me that her supervisor Pravishee Kella would called me in 10 mins. 24 hours later nobody has contacted me!!
