double debited my account

On the above mentioned date, I specifically paid off the contract prematurely according to the billing they had quoted me. I followed all their instructions to the tee as I've done this numerous times, but this time around I'm made to suffer the early payment consequences cause of someone in the cancellation dept who didn't cancel out the contract. Month end of Feb, an extra amount of R617 was taken from my bank account & I've been fighting to be reimbursed but im taken from pillar to post. I spoke & emailed Moos King who i was told was the cancellations supervisor, whom as a supervisor is unreliable & inconsistent. At that time of our conversation, I was hospitalised & under great stress but he & his team found it rather amusing by placing me on hold. All i keep receiving is ENDLESS ref numbers & email addresses that don't work. On May 8 th 2015 @ 16:42 , I received a text message from Zolelwa Bonyula that I'll be refunded 3-7 working days. When that day came & went contacted Vodacom & another lady called Nyalleng Moahlodi followed up with her supervisor & gave me an email address that rejected on my end when I tired to send all supporting. It is now 4mths & I want my money
