Missed Payments for what????

I have been trying to apply for a car finance for the past months and days, Only to find out that i am being blocked by Compuscan Credit Bereau. Can you explain to me what is it that i am not paying and i have missed my payment on. All my accounts are updated and in order but Compuscan is saying i have missed 3 or more payments on my credit account. This is really frustrating can i get someone to explain this to me please.
