Mortgage Application- issue with rent account statement

CookandClean123

I was previously entitled to Universal Credit and they paid my rent directly in arrears. Since may i was no longer eligible and have paid myself however my mortgage application is has been declined by Kensington because of this solely. Its states on the Gov website it is paid in arrears so i have asked my broker to go back and explain but she has said they wont be interested. I just wanted to know do i still have a chance. Its a right to buy application so if it doesn't happen i wont be able to going forward as they are reducing the scheme this month.
