As shares plunged, some investors saw their money disappear
Claims would normally go to David Aaron Partnership but now they must go to the administrators at accountants KPMG.
The Financial Services Compensation Scheme (FSCS) will have to declare David Aaron to be in default, and that process could take a while.
The FSCS was set up to pay compensation to customers if they have a valid claim against a financial company which is no longer trading.
But there is a limit to how much money the FSCS can pay out.
Claimants get 100% of the first £30,000 they are owed, and then 90% of the next £20,000, to a maximum of £48,000.
Customers who think they have a mis-selling claim should contact KPMG in the first instance and it will then pass details of all claims to the FSCS for processing.
Anyone with a mis-selling claim should to get in touch with KPMG immediately at the address below:
