Bad Service - no technical and no armed response

We are very upset with the standard of service from Blue. We have called technical back a few times already with the new installation problems. We were called at 3am this morning due to a low battery. So obviously since we have double batteries installed my hubby went to check but I first phoned Blue and asked that someone meet him there to check and no-one arrived. He came back home, went back there, came back home and went back again a second time and still no Blue Security. So we are sending him into an area without protection despite paying a fee? Then this morning technical was supposed to meet us after 1:30 at the property to sort out faulty installation and its already 16:30 and no-one has arrived. So they expect a client to just wait around since 1.30 until whenever they feel they are ready to pitch? Basically the staff this morning thought it was laughable that I was worried about my husband being alone at a vacant property and despite about 5 calls to them nothing was done.... What exactly are we then paying for? When I spoke to them they didn't know my number - didn't know who I was and had me repeat myself about 5 times an then still no action!
