Cannot cancel a contract

<p>I have been calling the whole morning I have spoken to 4 different people but I cannot be assisted as I do not remember the contract number, finally someone calls and tells me my ID number is sufficient to check what my number is she gives me the number ans she puts me through to Faith who also ask me the same security questions but cannot help me because she has to transfer me to another person by now I am very frustrated she keeps saying she will transfer me but she puts me on hold for a while then she hung up. I have been calling and calling but now no one answers. I NEED to CANCEL this contract</p>
