This may be for a number of reasons. For example, you cannot sell loan parts if they are under seven days old and your account balance is negative. If you had a positive balance, you'd be able to place the loan part up for sale. In this situation, please either make a bank transfer or sell loan parts older than seven days old to rectify this. Your investments could be cancelled if you do not resolve this matter.
On occasion, there may be a system error preventing you from selling. Please contact the help centre on 0800 779 7706 if the problem persists.
