The number of complaints made to East Riding of Yorkshire Council has gone up by more than 9% in the past year.
It received 1,887 complaints from residents in 2017-18, compared to 1,728 in the 12 months before that.
A report to the council's cabinet also confirmed that the number of replies sent within 10 working days has fallen by 5%, which is blamed on a change to a new feedback system.
