CONTINUOUS DEBITING FOR MY CANCELLED CONTRACT

We cancelled out Telkom Mobile contract in September at the Gateway Telkom Store. I then was debited R99 in October for the cancelled contract. When I called the contact centre they said that it was an error and that my R99 would be refunded, but someone would call me on Monday to confirm. I have had to make a further four calls to the call centre and NOTHING has happened! I have then be contacting Telkom via Facebook since 18 November 2015 virtually every day and keep getting the same \pass the buck"answer that someone is looking into it and will get back to me shortly. My husband had four calls from Telkom yesterday and each call telling him a different story! I have now been debited R727.64 and want my money back! I cannot believe that a big and renowned company like Telkom can actually be so *********** and with a lack for a better word USELESS! """
