Blue Label Connect-Run for the hills when this company calls you!

BLUE LABEL ****ECT. This company contacted me some time towards the end of last year offering me a cellphone contract. In the end I rejected the phone as it was old and out-dated and cancelled the whole thing. But the debit orders continued despite my best efforts of reporting this to them. And now I just realised they listed me on credit bureau when I owe them NOTHING at all. And now when I try to call them I still get passed on to numbers that either go unanswered or a not working at all.
