Life threatening incompetence from accounts department

We have been a client of ADT for over 17 years. We changed our bank from Standard to Capitec. All our 12 stop orders were changed from Standard to Capitec. ADT sent us a SMS stating that our account hadn't been paid this month. We went in to Capitec to query this and they said that ADT had loaded the stop order and had all the correct banking details. We have sufficient funds in the account. We then contacted ADT and the person in the accounts department confirmed that they had Capitec loaded in their system. She said that she did not know the person who sent the SMS , Guerra Ferreira, but said she would email him/her (she didn't know the gender). A message was left for them to call us today. No phone call. We are unable to speak to anyone who knows what is going on and no one calls back. Our alarm activated at 23:30, thankfully it was a false alarm, we did not receive a call from ADT. In the meantime we have no security.
