I have two sets of Citadel doors. I have been trying to contact the company for 6 weeks to purchase replacement parts. They put you on hold by phone for ever and do not respond to E-Mails. A very sorry company,I did not buy these doors originaly and would not buy anything from them ever after my present experience. I have just found out that two of the parts for the sliding door locks are not even availible any more and they are only 9 years old.
