Online application is misleading

I app**** for personal loan online wich i filled in and went through all the questions and gave all my information. I wanted 30 000 and the online application qaulified me for 66 000. I got my cell number incorrect wich i needed to rectify. I then started chatting with a online agent Devlin which assisted me and ask for certain details. An agent wouldve called me witin 24-48hours. I went to the branch to find out how far the application is, just to find out my application was blocked. Why didn't you block my online application or why didn't the agent advise me the application was blocked as well. The thing that bothers me is that the online application approved an amount. So no 1 called they sent me and email with why i didnt qualify. Thank you for your bad service.
