Barclays has received the highest amount of banking and credit complaints during the past 12 months, according to the Financial Ombudsman Service.
The ombudsman recently released its latest six-monthly complaints data, from January to June 2016, relating to all banks, insurers and other financial businesses.
A total of 169,132 new cases against all financial service firms were recorded in the first half of 2016, an increase of three percent on the previous six months.
The banking and credit division is one of six complaint categories within the data and made up 26 percent of the new complaints, with 44,806 new cases.
Off all the banks, Barclays had the highest number of these complaints made against it, with 8,212 cases. The bank also had the highest figure for the previous six months, when it received 7,612.
Of the recorded complaints against Barclays this year, more than 30 percent of the banking and credit cases were resolved in favour of the consumer.
The banking and credit category covers a wide range of financial products and services including debt collection, credit cards, leasing, overdraft and loans and many more.
Caroline Wayman, chief ombudsman, said: “Lots of factors can influence the complaints we see, from more people knowing more about their rights when things go wrong to external factors like volatility in the stock market or extreme weather conditions.
“I believe it’s important that we continue to share our insights into complaints to help businesses to avoid the mistakes of the past.”
The ombudsman only deals with complaints which cannot be resolved between a business and a customer, so these figures may only reflect a fraction of unhappy customers.
