Deadlines are not met, the estimate is redone without agreement with the customer. The object was not handed over, the masters were not paid off, they had to pay twice for one job, once in the DCS, the second time to the workers. The certificate of guarantee for the work performed was not issued, the jambs had to be redone at their own expense. The management of the DCS does not take measures to remedy the situation, thereby undermining its authority and reputation of the company.
