I Can't E-mail WhatsApp About The Ban They Put on My Account

My WhatsApp account was banned, I sent an e-mail to reopen it, but I received an answer saying "The possibility of requesting a review by e-mail is no longer available." In the reply email, it was written that I had to tap 'Send review request' on the WhatsApp application of the banned account, but I do not have this option in my account. There is only the option 'Sign up with new number'. I tried to write about the problem in the *contact us* section on their website, but it always gives an error while sending. Unfortunately, I cannot find anyone to whom I can convey my problem.
