Sold and NO service

Worst experience ever from a company/agent. We we're sold a house by one of your agents knowingly that the front door of the house does not lock and that there was never a key for the door. Not sure how your agents operate or think it's OK to sell houses without working locks. Instead I get told but there is at least a security gate, if this is how you guys operate then let this be a warning to other potential buyers. I had to get someone out to break the lock since it was damaged inside and couldn't be removed as easily as stated by your agent. Furthermore the previous owners still have a remote for the alarm system in their possession so I basically have a front door that cannot lock and someone with a remote to deactivate the alarm and there seems to be no urgency either as these issues are already from a week ago. I need this sorted out by someone who actually knows what they are doing.
