Unhappy client

I am really disappointed with the poor service delivery by Vodacom contractors. I had a 24-month contract with them that was finished without any problems.When I returned to acquire new contracts, it appeared that they had been handed over to legal. How is that possible? I finished paying for that contract after it was cancelled. The other Vodafone department confirmed that my account has been cleared. Why, after fulfilling my contract, is there still a legal ongoing issue? Even on Experian and ClearScore, my contract is explicit. Fix your mess before you lose a valuable customer.
