Iv Cancelled so stop taking my money!!!

I Called the 10210 on the 5th Feb in order to cancel my line and wifi, they said I need to give them one months written notice, the lady gave me the address to email the cancellation to which I promptly did. I was called on the 4th March to confirm that they had received my notice would I still like to continue with my cancellation, I confirmed with Telkom that I did, when I asked when my deposit would be returned the gentleman said it would be refunded soon. when I went home that evening my phone and wifi were disconnected. Two days later Telkom took my monthly fee from my account. I called them and after being on the phone for over 45 minutes they said that they have recorded a dispute and will get back to me in 48 hours, 1 week later I was called to confirm that they will know on the 15th april when I will receive my deposit and money they owed. They have since taken another months fee from me, I was on the phone again today trying to get some sense of when I was going to get my money back, the guy on the phone refused to help or put me through to someone, he put me on hold only to put me back into the system. I have been holding for 1 hour. WHEN WILL I GET MY MONEY!!!
