Katapult (formerly Zibby) review: Scam

I got a loan for a computer. The TOTAL for the loan is $1,599.99. I've paid to date $1,907.50, while my account says I still owe $1,448.22... So by the end of the payoff is $3,697...How this is legal I have no idea. DO NOT DO THIS. They market it as "No Interest" but after the 90 days they essentially double your total price. I've messaged them one or two times before confused about my payments and they kept giving me the run around. At no time did they say the total I'd end up paying is $3,697. They've said multiple times that my payments are going to the TOTAL LEASE, and when they've said this, I've said okay so the $1,599.99. And they've said yes, yet when I log in my account says that I still owe almost $1,500! I understand interest but 100% interest should not be legal. That's worse than student loans and lending club. The marketing when I applied also said it was INTEREST FREE
