Доработать форму заявки AmoCRM

A long run of project.

Not a contact customer.
The price is low.
In the project I culpably delayed the deadlines, but the customer did not respond to any agreements.
There are all kinds of inscriptions, you need to be more responsive.
Moreover, a few options of the code I have discounted. Unfortunately they didn’t get/not earned.
On a number of cases, there was a contact with the developers of the Amosrm. The screen starts http://prntscr.com/mtx5db
The task was harder than I planned, but I didn’t give up cooperation for the same price.
He didn’t leave a response for a few months – he wrote a proposal to do it without negative reviews, but the person appeared online but on the contact decided not to go (not answered not to a single message).
That is why I leave a negative feedback.
