Deleting Stripe

Booking.com has created and manages my stripe account which i have never used because I never went live. I now need to create a Stripe account for other purposes and can't because my email address is being used. Stripe has said the only thing I can do is reach out to support from Booking.com. I have contacted the email, and it responded with instructions for a phone number which is an invalid US number. The number Stripe offered is a Dutch number with no clear way to get it in English. How do I gain access to my Stripe account that booking.com has created or how do I reach Booking.com for support. I've emailed about 4 different emails through different access points.
