Collection Agency Charging Interest and Wants Bank Info

A collection company contacted me about a debt that that is only 2 months old. The person I owe just sent me a bill 3 weeks ago. This debt collector told me I was no longer eligible to contact the person I owe, and that all payments need now to go thru them. I was told that a down payment was required of one third of the total amount was needed to avoid a daily intrest accruing at a rate of 10%. I was also told that they needed my banking information was needed, including my banks routing number. Is this correct?
