Bad Account Management

I had a dispute with Vodacom over a contract I had with them 5 to 7 years back. Along the way I had renewed my main contract with them and during my renewals I had been made to understand that I have only one contract (which is my main contract). At the point that I realized that I have been paying the R185, I enquired through their call center about the R185 and nobody had a clue of any contract besides my main contract. I then cancelled the debit order. After three months I got a call to inform me that my account is in arrears. I explained my story about the enquiries and was told the matter will be investigated. I got sms saying my account has been handed over to the legal department. I called the lawyers Burnard Raaff and Associates and spoke to the lady called Sonja Gomez who informed me that Vodacom first sends you to the credit bureau prior to referring the matter to legal. On 17/09/2015 I decided to pay up whatever they required and was given a letter confirming that the amount has been paid in full and it takes seven days to clear from credit bureau. To date my name has not been cleared. My main contract is Smart L and I have been paying no less than R1200 per months.
