Regarding renewal of annual app registration fees

I've requested app development and am currently publishing it, but I can't contact the app development company and am unable to pay the annual fee to Apple. I don't know my registered account, so what should I do? I contacted Apple Japan, but they only handle personal inquiries and cannot handle business app development requests, so they suggested I post a question on this website. Thank you in advance.
