Cancellation and thieving vodocom

Still to this day vodocom has not cancelled my contract I paid over 8K to cancell contracts you continue to invoice me and it's now reflecting on my credit score as in arrears over 3 months ..DONT MAKE ME MAD I WILL BE TAKING YOU TO COURT FOR BREAKING YOUR OWN CONTRACT AGREEMENT with regards to cancellation .I have called millions of times emailed and spoken to team leaders who are so *********** and have not got back to me I have all the proof it's the second time I'm writing a review your response is pathetic on here
