I recently applied for UK visa which was refused. I overstayed years ago when I was in school. Thereafter in 2013 I was given a 6 Months visa which wasn't used. I then applied in 2017 for a Conference I was denied because I failed to disclose a court order in my application. I applied again last month but guess what? I was told they called my office number found on the website just to confirm my employment and the Front-Desk officer picked the call twice and tried to transfer to me without success. This recent application was to be sponsored by my Employer.

I had Letter of Introduction, Pay-Slip, Bank statement as evidence.

What do I do?
