Dial direct insurance cancelation

I filled an online form on Dial direct's website and requested for a call back. They called me the following day and i informed them of my intention to cancel the policy. The guy on the other side told me that he is in a different department and that he'll let the people from the cancelations department to call me, which they didn't.I got a number of calls from a Cape Town number and each time i pick up there was a faint sound, i couldn't hear it but it sounded like an automated voice message, all i could hear was "this is an important message.." furthermore i couldn't hear anything. I decided to call them yesterday, spoke to a lady, we chatted for a while and she asked me to hold while she's transferring my call to the relevant people. I stayed on the line for a while, listening to their irritating music. After something like 5 minutes or so she came back, told me that they seem a bit too busy then she confirmed my cell phone number and promised to have them call me.They never called me back, to my surprise they went ahead and debited my account. I need this resolved, the policy canceled and my money paid back.
