The project was undertaken by a stock exchange for a low budget. It would seem to have done a good thing.
As a result, from two banners (logotypes for market plays) the customer approved one, and the other began to be charged in the style of "no it at all", "we don't like it", and even when I made two new concepts on the sample provided by the customer, it was again "no it at all".
After all my efforts for the minimum budget to make the customer good readable logos (banner), the customer closes the project without payment and shows me low ratings on all points, although on the contact I was always, delivered the job in time, and the cost was minimal.
I don’t recommend collaborating with this customer because “we don’t like” you can say absolutely about any work and close the project, and using the results of your work you can’t track.
