Stanley Convergent Security Solutions

After months of deliberation we chose Stanley Convergent Security Solutions to help protect our home. They apparently don’t know their own profession for our well-​being has been compromised. Since installing it 3 months ago, we have had mishap after mishap occur. There have been a half dozen service calls, which have been handled as follows: promise of two days time in coming over to fix our problems, a tech who arrives late, then walks himself through using their guide as he tries to fix the errors, every time promising that this time, the problem has been fixed. They have blamed the errors on our wifi, have ordered parts that have taken 3 weeks to arrive and still the issues remain: 10 times being woken up in the middle of the night to the sound of our malfunctioning alarm sounding. Nothing like crying «wolf»!!! My husband has been unable to go back to sleep and work has suffered accordingly.
The original price for the system was quoted as $ 1700 and now they are requiring an extra $ 200 for no apparent reason. We do not want this contraption in our house and no one will come over to uninstall it. It has never worked and we refuse to pay them for their faulty product.
