The system DOES allow it becuase they have changed my DD date for me
I am also on SACM. them telling you they wont change it is BS (granted it took them along time to do it but it DID get done)
OB you really dont have a clue do you.....NTL have a obligation to change your DD date for you if you would like. Its not a case that they CANT because as I said mine has been changed. If they say they can't I would pack up and leave as its unacceptable for a company the size of NTL not to be able to provide such a service.
We don't want to hear your NTL licking anymore OB
