Poor service

We had alarm system installed early this year by Chubb but the after sales service that we got is to say the least pathetic,i asked numerous times for the siren to be moved due to the fact that you can not hear the siren when the alarm is activated as it was placed in the cupboard of the main bedroom but nothing is happening but every month the debit order goes off no problem.<br> <br> We are also still waiting for the Chubb display boards which we never received and after numerous requests still nothing<br> <br> My contact number is ***
