Debit order

I called into your call centre to re-activate my debit order that I asked to be put on hold as I was not working. I now working again and I would like to activate the debit order facility. My details did not add up as per the consultant who assisted me. What details do you have on the system exactly? Can I just have the debit order activated so that I can stop getting nasty sms's. You people are quick to sell contracts but slow to provide assistance when required and quick to call when no payment was received. Can someone please sort out my problem as calling your call centre clearly never does work.
