just put a lean on them. they are so easy to do. the person cant sell anything unless they pay for your lean against them.
my brother was a victim of a lean. he had his carpet put in but the guys who did it had seams and lines everywhere and looked horrible. my brother never signed anything ad they put a lean on him b/c he said i am not paying for this. he had to pay it and they never changed the carpet!!!!!!! talk about rape. so i think you have a chance.
