Authorhouse Publishing UK review: 2 books printed, no payment for sales

In 2005 I wrote two books and had them self-published by Authorhouse in the UK. I knew they had sold a couple of books. When I asked them if I could have what little money there was, they said they only paid out somewhere about now, October /November. I have not had a penny paid to me yet. I am a pensioner and would like that money paid to me. I have no ways of finding out how many books they sold. They have not kept in touch with me.
I would appreciate your help.
