ADT security *****s from a 11 year old girl

Recently there was a break in at my home. This was around 2.30 am and the activation on our alarm disturbed the intruder/s that didn't get into the main part of our house (lounge etc). My daughter's 7 inch tablet was on the lounge coffee table afterwards. The only people that were in our home after the break in were two ADT personnel and two SAPS personnel. Before the ADT guard could leave, he insisted on testing the alarm with me. He was left unattended in the lounge while I was in the bedroom which is where the key pad to the alarm is situated. The next morning my daughter realised her tablet had been ****** from the lounge. The Area Manager, Carlos Barbosa was of absolutely no help and the case was then handed over to Steven Botha, Regional Armed Response Manager: Central was equally unhelpful. We have not been able to resolve this issue even after agreeing to paying for lie detector tests etc. We have paid ADT on a monthly basis for more than 10 years to protect my family and property ultimately violates the safety of our home and the belongings of our 11 year belongings of our 11 year old daughter.
