Telkom *****ing

I went to cancel my contract as we will be immigrating and your employee told me my contract will end the end of June and that there will be NO MORE DEDUCTIONS FROM MY ACCOUNT!! He even gave me a temporary pre paid sim for the time being. But what happened the end of June, you guys tried to take a debit order off, a totally different amount as well!! I laid a ticket with you guys AND still no one phoned me!! Really pathetic!
