UPDATE- I have been talking with my attorney that I use for the business, He advised me since there was never any compalints or issues brought until the day they cancelled the contract, with never any warning or cause to cancel- I guess saying they are not happy is not valid cause to cancel contract without warning,chance or sit down to talk about issues is breach of contract. I took photos of each property the day after they cancelled the contract to show it was in good looking order besides it was our cutting day for them that week. I didnt take any before photos but my attorney went online and contacted the listing agent that the contract holders just purchased and got copy's of the pics they took when listed. I now take before pics of any new jobsite before we do one min. of work on site and put in there file. In my commerical contracts we have in there if you cancel during length of contract 50% of remaining balance is due within 30 days of date of cancel. My attorney sent them a letter saying they owe for apirl then the 50% left of contract with payment due in 10 days is demanded. We will see what they say this week.
