Inexcusable Poor Service

Moved home. Wanted to transfer my line. Put in order in November which got cancelled, put in a new order in December, waited over a month kept phoning in, it got pushed up to "Escalation Status" but no one got back to me. Called in twice, and now it's on a new system, and due to the escalation they can't book a date for the technicians to come out to my new residence. Emailed them, got a call to say they'd fix it, then nothing. I called back in two days and my order was cancelled, without my consent. Placed a new order middle January, said it should take 7 days, left them alone for a week, called this morning and the NEW order has been cancelled, again, without my permission. Then, to place a third order, they couldn't give me an order number, said it will be sms'd. This is inexcusable. This is ********** service. They hold you to ransom as we need a land line and fast internet. It's incorrigible. I am flabbergasted. I can't complain to a Manager either.
