Unauthorised contract Activation

Now you have activated another line on my account without my permission, you are incurring charges on my account, you will pass your debit order through my bank and then make me wait one month for the refund. And you remain unreachable to cancel or query or report this mistake of yours. Is this your way of forcing new business? Sending something that was never ordered and just start billing the person and make it impossible for them to get hold of you to tell you of your mistake. I have tried again today many times to reach you on your cancellations line.
