Vodacom poor service and Rude Agents

Rudeness of Vodacom cancellation department. I have trying to cancel my Vodacom account since Monday the 19th of April. I was made aware that my account have pre-legal status and logged the query to remove my status as I have paid the arrears. I was given the reference number ***. I have confirmed with customer agents that the Pre-legal status has been removed from my account and now I can cancel my account. I have called Vodacom cancellation department got agent name called Thato he confirmed that he cancelled my account and i will received confirmation e-mail and did not come through. Called again and got the Rude agent name called Sharon. Sharon said my status still says pre-legal and is not cancelled and quickly dismissed my call. Tried to call Vodacom call center and they flagged the number that i am calling with and I cant hold of Vodacom call center.
