Rcs keep declining my application because of debt review of 10 years ago

I app**** for a makro account underwritten by rcs they said that it declined. I contacted the call center and they put me through to new accounts then the lady informed me it was declined because it was 10 years ago under debt review and was handed over to the lawyers then I asked her what is the solution to the issue because I app**** for a car and was approved only by rcs I get declined. Then I asked her does it mean then I should never apply because then It mean I will always get declined then she told me to contact itc. But on itc it show nothing of rcs. So the call center or rcs don't give me a way further.
