失职

As a property agent, we advise on the procedures and general policies. BUT during a recent case, I have given the wrong information, which caused that my client has to change the whole plan. 

I feel so sorry, and kinda of unforgivable. It should not happen. 

I know things happened can't turn back. Think about it, I should be more cautious in the future. I am doing it as a professional, and helping clients in house, which involves a lot of money. Mistakes such as this is not allowed at all. 

This is a stain on my career. :(
