How come it was NEVER picked up and line never suspended due to unpaid d/o

How does your billing work? If I didnt move homes and advise you of the amount due to me which is more than 3mnths there was no way you would have picked it up, why did anyone not pick up the unpaid debit order, suspend services etc, now I owe you 7k -jokes write themselves at Home connect...So you are a robot system with no humans that you do not actually check customers history and billing...
