No response from ADT. Poor service in PMB

Adt does not respond when the alarm goes off. When they are contacted they pretend not to have gotten the signal. On one occasion it mistakenly went off and we contacted ADT to find out what happened and the consultant who answered sounded like she just woke up and just appologised. Its just been a very bad experience since we took out the contract and really poor service with them on many occassions. Staff are arogant and rude as well.
