Poor Poor service

My contract with autopage has expired and I have decided not to renew my contract and now Autopage has blocked my mobile number . Which is a number I used before I was even contracted to them . when I call the call center I am told it can't be fixed right away . I need my number as this is an inconvenience to my life . I owe them nothing so I don't understand the reason my number has been blocked all my business has been disturbed at the moment because of *********** people .
