Over 100 complaints were made to the Ombudsman last year from people in Mayo.
The 2020 report shows that, nationally, complaints to the Ombudsman about public services fell by 6% last year compared to the previous year.
3,418 complaints were made in 2020, a third of which related to government departments, while one-quarter of complaints were about local authorities and one-fifth regarding the health service.
Of the almost three and a half thousand complaints made last year, 101 were from Co Mayo, 180 from Galway and 43 complaints from both Sligo and Roscommon.
The Department of Social Protection, Dept of Agriculture and Revenue Commissioners attracted the most complaints pertaining to Govt departments.
38 complaints were received about Mayo County Council - 6 of which were upheld.
One of the case studies highlighted in the annual report relates to a woman called Maria, who complained to the Ombudsman when Mayo Co Co refused her application for a council loan to buy her house.
The council refused the application because of rent arrears, but she said the arrears on her account were due to a council error, and she was repaying the arrears at the time her loan application was being considered.
The Ombudsman noted from the council's files that there was an internal memo from the Housing section to the Council's Loan Credit Committee, recommending that Maria be approved for the loan, and pointing out that the arrears were not as a result of non-payment of rent.
In addition, the Council's credit policy provided that, in certain circumstances, a person can make a loan application even if they are in arrears.
The Ombudsman said Mayo County Council should review Maria’s loan application.
The Council agreed and her loan application was subsequently approved.
