Declined application

I recently put an application through via your online platform which was automatically declined, I received a generic answer which is “ you do not meet the credit criteria “ If you look at my record, I have an outstanding credit score and more than enough affordability as stated by your employee Lyle, who then advised me that there is no actual reason for the decline. You have now put me in a position where my ITC has a decline noted which will affect any future credit facilities I might apply for. This is totally unacceptable. Your employee advised me that I should apply again in 6 months, however in 6 months time nothing will have changed on my profile so what is the point?
