LandlordInvest Limited, trading as Mustard, aims to deal with complaints fairly and promptly. You can complain by email to [email protected], by phone on 020 8323 3150, or by post to Complaints, LandlordInvest Limited (trading as Mustard), 3rd Floor, Great Titchfield House, 14-18 Great Titchfield Street, London, W1W 8BD. You can also tell any member of our team, and they will pass your complaint on. Please give us as much detail as you can, including your account or loan reference.
We will acknowledge your complaint promptly, normally within one business day of receiving it (it may take longer if it arrives by post). If we resolve your complaint by the end of the third business day after we receive it, we will confirm this to you in writing and tell you that you may be able to refer it to the Financial Ombudsman Service.
We will investigate your complaint fairly and keep you updated. We aim to send you our final response within 30 days. In any event, within eight weeks of receiving your complaint we will either send you our final response or write to explain why we are not yet able to, and when we expect to.
If you are not satisfied with our final response, or we have not sent one within eight weeks, you may be able to refer your complaint to the Financial Ombudsman Service (FOS) free of charge. Most individuals and small businesses can use the FOS, including lenders, IFISA investors and borrowers; the FOS will tell you whether it can consider your complaint.
You must refer your complaint to the FOS within six months of the date of our final response, which will explain this. The FOS contact details are:
