A total of 2,386 complaints were made by people about the authority during 2024-25.
In the report, the council said 952 investigations were carried out as a result of the complaints.
Other examples it provided include complaints relating to children’s services, revenues and benefits, waste management and housing.
Of the actions taken in response that were recorded, 56% were to provide an apology, 16% included giving extra information or explanation and 11% were actions linked to arranging employee training or guidance.
The report set out a number of areas to focus on for the year ahead in terms of how the council applied its complaints procedures and gets and responds to customer feedback.
They included staff training and focusing on the quality of their responses and response times.
“Complainants often highlight disappointment that they were not contacted, were not communicated with enough or information was not shared effectively,” the report said.
“More effective communication at an earlier stage can lead to a better understanding of the issues or the processes council staff work to – and prevent the development of a formal complaint.”
