Copper Mobile review: The app was useless and this company was disorganized

We worked with Copper Mobile and it was awful project and work. We have signed the contract and the management was so disorganized and the owner cancelled all the meetings. We had the project, which was connected with the app, and the company provided the project manager, who disappeared after the second meeting. They said that he worked on other project and after couple of weeks we found out that this person quitted. They changed managers, tactics and in result the app, which we created with them, was useless.
