Cancellation Request Repeatedly Ignored

I have been trying to get someone to assist with my contract cancellation request for over 2 weeks now. My mails have been ignored. I called the *** number today and got barraged with a number of ridiculous questions on the new authentication system, which has very out of date info (apparently from the credit bureau), and subsequently \failed\" their tests to prove I am who I say I am. I was then told it takes 3 hours to unlock my account and then I can try again. I flipped my lid and demanded a supervisor and was told they're all in a meeting. I was promised a call back...no call!!!! All I want is to find out what I owe this pathetic NON-service provider so I can legally cancel my contract as we are immigrating. You are forcing me to simply close my bank account and leave and force YOU to try and find ME because you're useless. How can this be so difficult? I simply want info and an amount so I can work out what I need to do and I have to just about provide DNA samples?! Is this what you call customer retention? I am disgusted and irritated and once again, SA proves what **** service providers we have!!!!!"
