Disappointing security service

My dad is 81 years was asulted at his home this morning. There was an attempt house breaking by 5 men. The one guy hit my dad on his head with the butt of the gun. The house is supposed to be protected with a alarm system form Mzanzi. My niece press the panic button but they didn't respond unless I called to notified them. I call numerous time during the day find out why the alarm was not working and was kept get pushed to technical department and no response. The staff apparently didn't give the technical manager message to call me. The technical guy eventually came to my dad's place and apparently did a temporary fix but still doesn't work. Worst security company to deal with.
