Thousands of customers lost their investments following the collapse of the microfiance company in 2015 when Mr Mahama was the president.
There were suggestions that Mr Mahama's wife had shares in the rogue company as many of the customers claimed that the former first lady urged them to save with the financial institution.
Speaking at Wamfie in the Dormaa East Constituency of the Brong Ahafo Region on Saturday Mr Mahama noted: “When we were in office, the NPP lied that DKM belonged to my wife and I.
"Today, you are in power, you know who DKM belongs to.
"You promised that you will collect the people’s money for them when you come into power.
"Please collect their DKM money and give it back to them.”
