Address for Yellowdale

If it is not on their website, they probably wont give it to you. Email them.

Yellowdale is not actually a lender. Rather, PDLs, mostly illegal, use it as a front. The webpage of Yellowdale says that they don't directly loan. They take application for loans from consumers and match them with companies willing to underwrite loans. In other words, Yellowdale is just a mediator. You need to take a look at your credit report to find out who is the actual lender that you borrowed from.
