Ruined my credit for nothing

Very unhappy. I app**** for a pre-approved loan on the app. I got to quote and pre-agreement, read the pre-agreement, and when I went back to actually continue with the loan, the application just disappeared. Now the application has expired because you failed to get in contact with me swiftly after I asked for assistance. And basically, my credit is now ruined because I have a hard inquiry on my credit report for NOTHING. Very disappointed.
