No payment for work done

React alarm ( Dealership for ADT ) gets sub-contractors to do work for them, after work is completed they promises payment each week and every week they don't pay with another promises - but wail you work for them the already advertise for new sub contractors to start work, probable because the don't pay what they should just to miss use the new idiot that starts working for the company. I have stopped all work because of no payment and promised to do more work after full payment was done and still no payment from them. I would just like to warn people to work for this company ( React Alarm ) as they will receive payment the first week or two but from there on they will stop payment or they will pay half or non of the payment will happen and you will work and get miss us and your vehicle, petrol and accessory's to do get there work done for free. They send you with faulty transmitters to client then send you back with transmitters that's not loaded with ADT reaction with no extra compensation for work done, and still force you to go back another time on own cost to fix there problem and then refuses to make payment because of there mistakes.
