Telkom champions in customer cash heist

I got a cellphone contract with Telkom mobile and its happed that last month a debit order bounced and had to diposite outstanding funds directly on their account. Now I'm being charged R202 for that. This is a day light *******, I don't care if it's on Telkom contract clause. They should look into this, refund my money and make necessary changes on their terms and conditions. If that doesn't happen I'm cancelling the contract like I did with cellc and will never again deal with Telkom.
