Around 680 complaints in the banking and finance category related to financial difficulty, Mr Untersteiner said.

He added that a key category of complaint was around delays in early release of super, while other top categories included loan break costs, disputed transactions and requests to extend payment terms.

Mr Untersteiner said a significant proportion of these complaints came down to poor communication from the financial services provider, as customer query numbers soared in the wake of the crisis and firms struggled to keep up.

“Many of these complaints result from poor communication, where a consumer has trouble contacting their firm, does not understand their policy or is confused about the information they receive,” he said.

“We encourage financial firms to minimise COVID-19-related disputes by communicating with consumers early, speaking in plain English, proactively setting customer expectations around delays, reviewing internal dispute resolution processes and regularly engaging with AFCA.”

Mr Untersteiner said the ombudsman expected to see a continuing increase in complaints in the following months, particularly until the end of the early release of super scheme in September.
