Four months cancelled contract and still paying!

After going to the Tokai store, and asking for a pre-cancellation on my contract, they requested the amount from Vodacom who then came back with an amount for me to pay. I paid the amount on the same day and took the proof pf payment to the consultant, Sassman, who originally assisted me. The consultant then emailed the paperwork to Vodacom and asked if I wanted a prepaid number, which I rep**** yes. The store then told me it would take 24 hours for the change to occur.

Four months later, I'm still trying to port my number to Telkom and Vodcom is now telling me that I cannot do so as I owe them money even though all the paperwork and communications were finalized.

Now the store is refusing to take my calls and continuously reassure me that they will call back , but I'm still waiting.
